Last change on this file since 15b34fd was 15b34fd, checked in by James M. Kretchmar <kretch@mit.edu>, 17 years ago
Fixed some small memory leaks in logging if files unwriteable If the variable logfilter is set it names a filter. Any messages matching this filter are logged. This is an independent mechanism from the other logging variables. If you want to control all logging with logfilter the other variables must be set to their default (off) settings. [BZ 37] Relatively substantial changes made under the hood to support filter logging. Now have more consistent interfaces to creating messages etc. Still needs more work though.

32.1.11-pre-1
4        Don't crash doing zlocate with bad tickets. [BZ 12]
5        Metion the path for the owlconf in intro.txt [BZ 54]
6        Print better error message if startup fails due to unreadable
7           .owlconf [BZ 57]
8        In load-subs: Print an error message if the file is unreadable or
9          doesn't exist, UNLESS load-subs is called with no arguments.  In
10          that case only print an error if the file exists but isn't
11          readable.  Still prints an error either way if zephyr reports a
12          failure. [BZ 19]
13        Fixed some small memory leaks in logging if files unwriteable
14        If the variable logfilter is set it names a filter.  Any messages
15          matching this filter are logged.  This is an independent
16          mechanism from the other logging variables.  If you want to
17          control all logging with logfilter the other variables must be
18          set to their default (off) settings. [BZ 37]
19        Relatively substantial changes made under the hood to support
20          filter logging.  Now have more consistent interfaces to
21          creating messages etc.  Still needs more work though.
22
232.1.10
24        Fix a new problem finding libdes425
25        Don't crash on very long hostnames [BZ 52]
26        In 'sub' command, create .zephyr.subs if it doesn't exist [BZ 15]
27        A fix for certain resize crashes (partly from alexmv) [BZ 55]
28        Turn off ISTRIP (gildea)
29       
302.1.9
31        Include /usr/include/kerberosIV if it's found
32       
332.1.8
34        Do OLC formatting for anything coming from olc.matisse
35        Improvements to popup size algorithm (from gildea)
36        Improved 'show colors' with non-colored labels
37       
382.1.7
39        The colorclass command is added, to make colorization easy
40        Handle MIT Athena OLC zephyrs correctly
41        Updated ktools website / bug address
42        Do ntohs() when printing zephyr port in zephyr info
43        Updated man page
44       
452.1.6
46        Fixed three bugs found by Valgrind.
47        Fixed a case where doing "aim addbuddy" instead of "addbuddy aim"
48          would cause a segfault.
49        pexec will now incrimentally display data as it is output
50          by the child process.  Additionally, commands running under
51          pexec may now be killed by quitting out of the popless window.
52        Added muxevents select loop dispatcher.  File descriptors may
53          be registered with muxevents and handlers will be dispatched
54          to when data is available for non-blocking read/write/except.
55        Switched the stderr_redir stuff to use muxevents.
56        Print C-\ correctly (from gildea)
57        Dropped first brace in muxevents functions for consistency
58        Catch SIGHUP and SIGTERM and do a proper logout
59       
602.1.5
61        Added a licence
62        The 'personalbell' variable can now be set to 'on' 'off' or
63          the name of a filter to match against
64        The 'loglogins' variable now controls whether login/logout
65          messages are logged.  It is off by default.  For now this
66          affects only AIM messages, later zephyr login/logout messages
67          will also be logged if this is set to 'on'
68        Added 'show license'
69       
702.1.4
71        Normalize and downcase AIM names for logging
72        Fixed a bug where sending a null zsig could cause a crash
73        Better 'away' toggling if only one protocol is away.
74
752.1.3
76        Added perl filter elements.  Similar to having "filter <subfilter>"
77          in a filter, you may also have "perl <functionname>"
78          where <functionname> is passed an owl::Message object and
79          returns 0 or 1 depending on whether the message matches
80          that element of the filter.
81        Don't print an error about loading subs if there is no
82          .zephyr.subs
83        Do the initial zephyr_buddy_check when pseduologin set to true.
84        Updated man page
85       
862.1.2
87        removed unused filter_depth variable
88        Fixed memory bug on receiving pings
89       
902.1.1
91        Filters of filters now work.
92        Removed the "possibly not readable" part of the config parsing
93          error
94        In the sepbar, reverse video the view name when it's not set to
95          view_home (as opposed to the static 'all').
96        The '!' key (bound to 'view -r') now creates a negative version of
97          the current view and switches to it.  i.e. "show me all the
98          messages that are not these"
99        Added the 'ignorelogins' variable
100        Log when outgoing personal message fails
101        Removed file descriptor from sigpipe catcher printer just for now,
102          since the field does not exist on OSX
103        Added an ifndef for socklen_t in libfaim/ft.c
104        Added the 'aim search' command.  The popup on callback may be
105          dangerous, should switch to an admin msg for results, or add a
106          new event queue
107        First pass at AIM away messages.  It is a little different from
108          what most clients seem to do, in that an away reply is sent for
109          each message received.  Most clients only reply to the first one
110          per away-session.
111        Now have a set of 'aaway' commands and variables just like the
112          'zaway' ones (except that changing the 'aaway' variable talks to
113          the server)
114        The new 'away' command does everything for both AIM *and* zephyr.
115          There is a known funkiness here, where if you turn one away on,
116          and then use 'away' (or 'A') to toggle, you will turn on off and
117          the other on.  Just leaving it for now.  Should do better in the
118          next patch.
119        The 'A' key is bound to 'away'
120        Status bar can now read AWAY, Z-AWAY or A-AWAY.
121        Changed C-n to scroll down just a line in popless
122        If the config exists but is not readable, print an error before
123          exiting
124        Only print forced AIM logout message once.
125        Don't bind F1 to help in edit context
126        Fix bug in 'getsubs' with no tickets
127        New code for getting users from .anyfile
128        Added the 'pseudologins' variable, and code to do it
129        new attributes 'pseudo' 'logintty' and 'loginhost'
130        Don't print extra new lines in popless_file
131        New zephyr_get_field function
132       
1332.0.14
134        Fixed missing word in startup message
135        Better 'status' command
136        Use '+' for popwin corners when 'fancylines' is off
137        Allow TERMINFO to be overridden in the envrionment
138        Command line arg -D turns on debugging and deletes previous
139          debugging file
140        Do ~ expansion in 'dump' command.
141        Current directory added to 'status' command
142        Massive changes to libfaim and aim
143       
1442.0.13
145        Changed startup message for new mailing list
146        blist now prints AIM info even if .anyone is unreadable
147        Catch SIGPIPE and print an error rather than crashing.
148                [It's possible that this may have some portability
149                issues under Solaris and we may need to add some
150                configure stuff around SA_SIGINFO...]
151        Handle the case in aim_bstream_send where aim_send returns -1,
152                although there is likely an underlying problem here
153                that would lead to this case.
154        Print the username on aim login failure, not something random like
155                the password.  ;)
156        Un-word-wrap text when sending AIM messages.
157        Replace the main loop continue in the keyboard handler with an else.
158       
1592.0.12
160        Command history now doesn't allow the last entry
161           to be repeated
162        If format_msg returns "" print "<unformatted message>"
163        Better align oneline admin and loopback messages
164        Print an admin message indicating when subscriptions can
165           not be loaded on startup
166        Set aim_ignorelogin_timer to 15 by default
167        Admin message on login/logout of AIM
168        Fixed double quoting in smartzpunt
169        Added timestamp to login/logout messages
170        Fixed replies to loopback messages
171        Fixed smartnarrow on classes/instances with spaces
172        Added the 'loggingdirection' variable
173        All loopback messages log to 'loopback' now
174        Print an error message if trying an invalid color for a filter
175        Fixed bug causing > not to go to end of editwin every time
176       
1772.0.11
178        Updated basic help
179        Display CC: in outgoing CC messages
180        More AIM logout detection
181        Don't proclaim "interfaces changed" on first build.
182        Added the 'loopback' message type
183        Added the 'loopwrite' command
184        Added a timestamp to the default style
185        Zpunt now works with weird regex characters

198        Added feature for capturing stderr messages
199           from commands and displaying them in the errors buffer.
200        Create an admin message explaning that a zephyr couldn't
201           be sent
202        Better reporting of perl errors (both into the errqueue
203                and also clearing the error after displaying it).
204        Allow default_style to be specified in config.
205        Added errqueue

211        Fixed bug with idle times causing broken pipes.
212        New libfaim
213        Added the 'source' command.
214        Make sure that a newline is always at the end of messages
215                returned by perl style formatting functions.
216        Add owl::login and owl::auth to legacy variables populated for format_msg.
217        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
218        Add base methods for login_host and login_tty
219                and others that return undef.
220        New API for perl message formatting functions. 
221                Legacy variables are still supported for owl::format_msg
222                and owl::receive_msg, but these functions are now also
223                passed an owl::Message object which contains methods
224                for accessing the contents of the message.  See perlwrap.pm
225                (and docs TBD) for the available methods.
226                *** WARNING:  The exact API for owl::Message has
227                *** not yet stabilized.
228        Added "style" command for creating new styles.
229                Usage:  style <name> perl <function_name>
230        Added support for "show styles".  Changed global style table
231                from list to dictionary.
232        Changed AIM password prompt from "Password:" to "AIM Password:".
233        Messages are reformatted after a window resize to allow styles
234                to take into account the width of the window.
235        When perl throws an error, the message is put in the msgwin
236                if possible.
237        Added perl functions for:       
238                owl::getcurmsg() -- returns an owl::Message object for
239                                    the active message
240                                    in the current view.
241                owl::getnumcols() -- returns the column width of the window
242                owl::zephyr_getrealm() -- returns the zephyr realm
243                owl::zephyr_getsender() -- returns the zephyr sender
244        Made owl::COMMAND("foo"); be syntactic sugar for
245                owl::command("COMMAND foo");
246        Added perlwrap.pm to contain perl code to be compiled into
247                the binary.  This is transformed into perlwrap.c by
248                encapsulate.pl.
249        Renamed readconfig.c to perlconfig.c and changed variables accordingly.
250        Minor bugfixes in cmd.c and commands.c

295        Added the 'toggle-oneline' command
296        The 'o' key is bound to 'toggle-oneline'
297        Internally, the one view now has a name, 'main', and message
298          recalcuations are done in place when its filter is changed.

335        Moved newmsgproc stuff to a function procedure
336        Added the 'newlinestrip' variable, on by default, that strips
337          leading and trailing newlines from incoming messages.
338        Fixed a case sensitivity probelm in owl_message_is_personal and
339           owl_message_is_private
340        The message object now uses a list of attributes internally, in
341          prep. for supporting new messaging protocols
342        owl_function_info now uses fmtext instead of one staticly sized

345          cc.
346        Added some defenses against resize crashes, and put in debug

348        In filters 'true' and 'false' are now valid tokens.
349        The 'all' filter has been redefinied to be 'true' and there is a

371          will be executed when new messages arive that match the
372          alert_filter
373        added the 'term' command which takes the 'raise' and 'deiconify'
374          options.  It assumes xterm for now.
375        only 'make distclean' will nuke core and ~ files now
376        fixes to owl_function_do_newmsgproc from Stephen
377        converted functions.c to new code style, which I'm giving a shot
378        Makefile.in: define DATADIR, for default owlconf.
379        Makefile.in: provide "all" and "install" rules.
380        configure.in: try also libdes and libkrb4, for people using heimdal
381        configure.in: see if des_ecb_encrypt is already prototyped.
382        configure.in: minor changes to work with new autoconf without needing acconfig.h.
383        configure.in: find the install program.
384        configure.in: test for use_default_colors since some versions of
385          solaris don't have it, so we can at least compile something
386          vaguely working there.
387        keypress.c: ifdefs for keys not defined on at least some solarises.
388        owl.c: don't call use_default_colors if we don't have it
389        readconfig.c: added *commented out* code to try to find a
390          system-default owlconf if the user doesn't have one.  Have to
391          ponder if I want this
392        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
393          des.h.
394        zcrypt.c: include owl.h so we get the configure-generated config.h
395        Change to codelist.pl to deal with new code style
396        Remove some ancient stuff from zcrypt.c
397        General cleanup to Makefile.in
398        CTRL and META are now OWL_CTRL and OWL_META.  OWL_CTRL moved to
399          keypress.c
400        do_encrypt declaired static

404        Added basic AIM support, including the "aimlogin", "aimwrite" and
405           "aimlogout" commands
406        New built-in filters 'aim' and 'zephyr'.

430       
4311.2.7
432        Outgoing messages now go through the config for formatting
433        Zaway now makes an outgoing message, instead of an admin message
434        The 'zlocate' command can now handle multiple users

450        Added search, '/' and '?' to basic help.
451        Will attempt to keep the current message as close as possible

471             'tty' variable before setting the zlocation
472        There is now a 'zlist' command that acts like 'znol -l'

479        The built-in personal filter is updated to do so
480        Fixed a bug in moving the pointer after an expunge
481        Fixed up the normal scrolling code.  Now it should always
482          land on a message, but it's still not optimal.
483        Added the variable 'smartstrip' which will strip kerberos
484          instances out for the 'reply' command.
485        Added -R/usr/athena/lib to the build for Athena
486        Started updating the intro document
487        Small changes to help / about
488        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
489          update .zephyr.subs by default.  If either is given the '-t'
490          (for "temporary") option the .zephyr.subs will not be updated
491        Turned off beeping for hitting the top or bottom of the list of
492          messages
493        Made daemon.webzephyr a special case for smartstrip
494        Added 'out' as a default filter for outgoing messages
495       
4961.2.3
497        Added filters "ping", "auto" and "login" by default.
498        Added "body" as a valid field to match on in a filter.
499        Temporary fix to bug where C-SPACE would cause the key handler to
500             lock up.
501        Messages now have a direciton (in, out or none).  Filters can
502             match on this direction
503        Outbound messages are no longer type 'admin' but are of the
504             appropriate message type (i.e. 'zephyr') and are direction
505             'out'.
506        Smartnarrow now works on outgoing messages
507        'info' updated to show more information for admin and outgoing
508             messages
509        Renamed pretty_sender to short_zuser and renamed long_sender to

511        Moved zsig generation to the zwrite object
512        Print the zsig used for outgoing messages
513        The tty variable now controls the zephyr location tty name
514       
5151.2.2
516        Added the 'search' command.
517        '/' is a keybinding for 'search'
518        '?' is a keybinding for 'search -r'
519        Fixed stristr, which was completely broken
520        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
521             and put it in functions.c
522        Attempts to stay near the current message when switching views.
523             When switching from an empty view to one we've previously
524             been in, the new current message position will attempt
525             to be close to the current position from the last
526             time we visited that view.
527        Fixed bug in readconfig.c that prevented building under perl 5.005.
528        Switched "C-x C-x" to only "startcommand quit"
529        'getsubs' prints closer to the order you sub in.
530        Modified the behavior of last so that "> >" will clear the screen.
531        The new behavior of last is:
532              Moves the pointer to the last message in the view.
533              If we are already at the last message in the view,
534              blanks the screen and moves just past the end of the view
535              so that new messages will appear starting at the top
536              of the screen.
537        Fixed a typo in the help for smartzpunt.
538        Fixed functions to handle curmsg being past the end of the view.
539
5401.2.1
541        New framework for command handling.
542        New framework for keymap handling.
543        Added commands for everything that is bound
544             to a key (do 'show commands' to get the full list).
545        Added 'multi' and '(' commands to allow multiple commands
546             to be specified on a line.             
547        Added user keybindings with bindkey command.
548        Added command aliases (eg, "alias foo bar").
549        Added undelete command that parallels the delete command.
550        Added additional options to delete command.
551        The reply command now takes arguments.
552        Added 'edit:insert-text' command.
553        Added 'show zpunts' to show active punt filters.
554        Added 'show variable <name>' and 'show variables'.
555        Added 'show command <name>' and 'show commands'.
556        Added 'show keymap <name>' and 'show keymaps'.
557        Added 'M-u' to undelete all messages in current view.
558        Fixed dotsend so that the zephyr will still send if there
559             is whitespace after the dot but not on the same line.
560             This should resolve an issue where dotsend wouldn't work
561             if you'd gone up and edited a zephyr.
562        Bug in page down fixed
563        C-t will transpose characters
564        Fix the scrolling bug where we would sometimes fail to scroll
565             the screen down, leaving the current message off
566             the bottom of the screen.
567        Refixed 'login or login' typo in help
568        Fixed M-u description
569        Removed 'first' and 'last' from basic command help
570        Added M-N to basic key help
571        Added M-D, M-u to basic key help
572        Fixed a quoting problem in configure.in
573        Changed top of help to use 'show' instead of M-x
574        Fixed a bug in the summary field for user-created aliases
575        Added "reply zaway" which sends a zaway response to the current msg.
576        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
577        Some buffer overruns fixed
578        Variables now have a summary and a long description.
579                Only the summary is shown with help.
580                The long description is shown with "show variable foo".
581        Added a 'scrollmode' variable which determines how the screen
582             will scroll as the cursor moves.  The default behaves
583             identically to previous versions of owl.
584             The following modes are supported:
585             normal      - This is the owl default.  Scrolling happens
586                           when it needs to, and an attempt is made to
587                           keep the current message roughly near
588                           the middle of the screen.  (default)
589             top         - The current message will always be the
590                           the top message displayed.
591             neartop     - The current message will be one down
592                           from the top message displayed,
593                           where possible.
594             center      - An attempt is made to keep the current
595                           message near the center of the screen.
596             paged       - The top message displayed only changes
597                           when user moves the cursor to the top
598                           or bottom of the screen.  When it moves,
599                           the screen will be paged up or down and
600                           the cursor will be near the top or
601                           the bottom.
602             pagedcenter - The top message displayed only changes
603                           when user moves the cursor to the top
604                           or bottom of the screen.  When it moves,
605                           the screen will be paged up or down and
606                           the cursor will be near the center.
607        Added owl_sprintf which returns the formatted string, or NULL.
608                The caller must free this string.
609                This will allocate enough memory and thus
610                avoid potential some buffer overrun situations.
611        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
612                message as having been sent.)
613        The "Not logged in or subscribing to messages" error
614                now includes the name of the recipient.
615        The "disable-ctrl-d" variable may also be set to "middle"
616                which will result in ctrl-d only sending at the
617                end of the message.  This is now the default.
618                This also added a command "editmulti:done-or-delete".
619        Fixed a bug in the "reply -e" command.
620        Always clear the command buffer before executing the command.
621                (So that interactive commands can sanely do start-command.)
622        Fixed preservation of e->dotsend across owl_editwin_clear().
623        Added history for multiline edit windows (eg, for zephyr composition).
624                The M-n and M-p keys will cycle through the history ring.
625                In particular, it is now possible to edit the command line
626                of a zephyr being composed:  C-c it and restart it
627                and then M-p to get the aborted composition back.
628        Added owl::send_zwrite(command, message) to the perl glue
629                to allow for the direct sending of multi-line messages.
630                For example:  owl::send_zwrite("-c foo -i bar", "hello");
631        Changed owl_fmtext_print_plain to return an alloc'd string to
632                avoid buffer overrun risks.
633        Added owl::ztext_stylestrip("...") function to perlglue
634                 which returns the ztext with formatting stripped out.
635        Added colorztext variable which can be used to disable @color()
636                 strings arriving in messages after it is set.
637                 (Currently, changing its value won't reformat messages).
638        Outgoing zephyr logging now obeys the logpath variable.
639        The '~' character in logpath and classlogpath now gets
640                 replaced with the user's home directory.
641        Added simple implementation of smartnarrow-to-admin that
642                 creates a "type-admin" autofilter.
643                 This was done mostly so that M-C-n and M-C-p do something
644                 sane on admin messages.
645        Added opera to the allowed options to the webbrowser variable.
646        Fixed some buffer overruns in the "reply" command.
647        When repying to "all" on a message that begins with "CC:" (eg, sent
648                 with "zwrite -C", the reply line will be constructed
649                 from the sender and the usernames on the CC: line
650                 of the message being replied to.
651        There is no such thing as C-R, so left C-r as it is but added:
652                 M-r --- edit reply to all
653                 M-R --- edit reply to sender
654        Added RCS Id strings to all files.
655        'show keymaps' shows details of all keymaps after summary list.
656        Added --no-move option to delete command.
657                In particular, delete-and-always-move-down may now
658                be implemented with
659                '( delete --no-move ; next --skip-deleted )'.
660        Folded the nextmsg and prevmsg commands and functions together into
661                one command which takes arguments.
662                Added '--filter <name>' option (eg, for next_personal),
663                '--skip-deleted' option, and
664                '--last-if-none'/'--first-if-none' options.
665                Help updated accordingly. 
666                In particular, the 'personal' filter is now used
667                for 'next personal'. 
668                Added --smart-filter and --smart-filter-instance options
669                to the next and prev commands.
670        Updated examples/owlconf.erik with the above.
671        Made owl_function_fast*filt return a string and not do the
672                narrowing, to make it more general.
673        Added a smartfilter command that creates a filter
674                based on the current message and returns the name
675                of the filter.
676        Added M-C-n and M-C-p keybindings to "move to next message
677                matching current" and "move to previous message
678                matching current"
679        Added variables edit:maxfillcols and edit:maxwrapcols which
680                will limit how wide editing paragraphs may get before
681                they get wrapped.  This is a max and may be narrower
682                depending on the current size of the window.
683                If 0, the max is unlimited.  Default is 70 columns for
684                edit:maxfillcols and unlimited for edit:maxwrapcols.
685        Added smartzpunt command with key binding of "C-x k".
686                This starts a zpunt command filled in with
687                the proposed zpunt.
688        Fixed a memory reference bug in delete and undelete commands.
689        Added support for perl to call directly back into owl.
690        Changed the implementation of owl::command("...") to immediately
691                call back into owl.  This allows perl to get the return
692                value of strings returned by owl commands.
693        Added the getview command which returns the name of the current
694                view's filter. 
695        Added the getvar command which returns the value of a variable.
696        Added an example to examples/owlconf.erik which uses TAB to
697                narrow and restore the view. 
698        Added an example to examples/owlconf.erik which uses M-c to
699                color messages matching the current one green.
700        Integrated change to fix problem with popup blinking on new zephyrs.
701        C-l and resizes will now refresh an open viewwin (eg, help).
702        Updated doc/code.txt to include info about filters, commands,
703                contexts, and keybindings.
704        Exec commands cleaned up to not have buffer-size limitations
705                and to not mess up spaces.  exec also returns a string
706                of the output now.
707        Integrated changes from 1.1.3, and added docs for "zlocate -d"
708                and new show commands.
709        Show with arguments produces help on show.
710        Fix a bug in readconfig caught by efence (where we'd try to read before
711                the beginning of a string if it was empty).
712        The perl command doesn't do makemsg directly, but instead
713             returns the string and it will get printed if it
714             was run interactively.
715       
7161.1.3
717        'show subs' and 'show subscriptions' are now the same as 'getsubs'
718        zlocate now takes an optional -d argument
719        'show terminal' / 'show term'
720        '>' / last doesn't set the last message at the top of the screen now

722        include 'default' in the 'show colors' list
723        added help for 'zpunt' and 'zunpunt'
724        changed the bug address in the startup message
725        can now do 'show status'
726        can now do 'show version'
727        'status' / 'show status' includes the owl version number now
728        'show terminal' includes whether the terminal can change colors
729        fixed off by one bugs in paging / scrolling viewwin
730        don't downcase the sender when getting the log name for personals
731        support @owl::fields as well as @fields
732        downcase class/inst filter names in auto filters
733
7341.1.2
735        Fixed memory mishandling bug
736        Fixed bug in redfining the filter attached to the current view
737        M-n will narrow to message, instance on non-personal, class
738             MESSAGE messages
739        M-N behavies like M-n except that on class messages it narrows
740            to class and instance
741        line wrap earlier, to account for tabbing
742        fixed typo in help
743        'status' command now displays info on terminal color support
744        zephyr @ formatting is now case independant
745        added support for color terminals
746        zephyr @color(foo) now works
747        'D' for deleted messages is now not bold, unless it's the current
748          message
749        F1 displays the help screen
750        added filter colors
751        added the 'colorview' command
752        added the 'show colors' command
753        users who don't have a .zephyr.subs get a simpler format for
754          incoming messages
755        If colors are available 'show filters' will show a filter in the
756          color associated with it.
757        Added the zpunt and zunpunt commands
758        Lines in the subs file starting with '-' are zpunted
759        Include login/logout messages in auto user filters
760        'V' changes to the home view ('all' by default)
761       
7621.1.1
763        Fixed perl, aperl, and pperl commands to deal with quoting
764              and spaces in a saner manner.
765        Removed all owl_get_* methods for booleans and switched
766              cases where they were used to owl_is_*
767        Changes to owlconf.erik to use some new features.
768        Increased the size of the help buffer (as it
769              was overflowing and truncating the help message).
770        Variables prefixed with a _ are not shown in help
771              or by printallvars (and prefixed Not Yet Implemented
772              variables with this).
773        Fix typo in help
774        include stdio.h in functions.c
775        remove stale "q to quit" from bottom of info message

837              a string not ending in a newline
838        Added 'X' keybinding which expunges and then switches to

857              and the owl_dict type.
858              These include regression tests.
859        Overhaul/rewrite of variable handling.  Variables are now managed
860              in an owl_vardict (in g.vars) which contains a dictionary
861              of owl_variable's.  Each owl_variable has dispatch functions
862              for validating values, setting it and getting it,
863              and for setting it to and from string values.
864              The variable.c file contains the list of variables.
865              Stubs for the owl_global_<varname>_get functions and friends
866              are generated from variable.c by stubgen.pl.
867              The help.c messages for variables now calls into variable.c
868              so all information about most variables is in one place.

874              to running owl_function_printallvars.
875        debug is now a variable that can be turned on and off.
876        Fixed mail,inbox message parsing in examples/owlconf.erik
877        Made zaway_msg and zaway_msg_default into variables
878        Changed owl_function_makemsg and owl_function_debugmsg
879               to use varargs (ie, so they can now take a format
880               string with args).
881        Don't allow " and \ characters in URLs with the "w" command.
882        Removed lots of build warnings.

890        Added appendtosepbar variable which may contain text which will
891              be appended to the sepbar.  This allows the configfile
892              to put information about pings and logins into
893              the sepbar.  (It may be worth also providing a variable
894              which enables this by default, but for now this allows
895              for experimenting with what works well.)
896        Added doc/code.txt which gives a brief overview of the code.
897        Added tags makefile rule and added TAGS to distclean rule.
