        Debian backports
        Change license to GPLv3
        general sprintf cleanup

2.1.11
        Don't crash doing zlocate with bad tickets. [BZ 12]
        Metion the path for the owlconf in intro.txt [BZ 54]
        Print better error message if startup fails due to unreadable
           .owlconf [BZ 57]
        In load-subs: Print an error message if the file is unreadable or
          doesn't exist, UNLESS load-subs is called with no arguments.  In
          that case only print an error if the file exists but isn't
          readable.  Still prints an error either way if zephyr reports a
          failure. [BZ 19]
        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.
        Deal gracefully with being resized as small as 1x1 [BZ 3]

2.1.10
        Fix a new problem finding libdes425
        Don't crash on very long hostnames [BZ 52]
        In 'sub' command, create .zephyr.subs if it doesn't exist [BZ 15]
        A fix for certain resize crashes (partly from alexmv) [BZ 55]
        Turn off ISTRIP (gildea)
        
2.1.9
        Include /usr/include/kerberosIV if it's found
        
2.1.8
        Do OLC formatting for anything coming from olc.matisse
        Improvements to popup size algorithm (from gildea)
        Improved 'show colors' with non-colored labels
        
2.1.7
        The colorclass command is added, to make colorization easy
        Handle MIT Athena OLC zephyrs correctly
        Updated ktools website / bug address
        Do ntohs() when printing zephyr port in zephyr info
        Updated man page
        
2.1.6
        Fixed three bugs found by Valgrind.
        Fixed a case where doing "aim addbuddy" instead of "addbuddy aim"
          would cause a segfault.
        pexec will now incrimentally display data as it is output
          by the child process.  Additionally, commands running under
          pexec may now be killed by quitting out of the popless window.
        Added muxevents select loop dispatcher.  File descriptors may
          be registered with muxevents and handlers will be dispatched
          to when data is available for non-blocking read/write/except.
        Switched the stderr_redir stuff to use muxevents.
        Print C-\ correctly (from gildea)
        Dropped first brace in muxevents functions for consistency
        Catch SIGHUP and SIGTERM and do a proper logout
        
2.1.5
        Added a licence
        The 'personalbell' variable can now be set to 'on' 'off' or
          the name of a filter to match against
        The 'loglogins' variable now controls whether login/logout
          messages are logged.  It is off by default.  For now this
          affects only AIM messages, later zephyr login/logout messages
          will also be logged if this is set to 'on'
        Added 'show license'
        
2.1.4
        Normalize and downcase AIM names for logging
        Fixed a bug where sending a null zsig could cause a crash
        Better 'away' toggling if only one protocol is away.

2.1.3
        Added perl filter elements.  Similar to having "filter <subfilter>"
          in a filter, you may also have "perl <functionname>"
          where <functionname> is passed an owl::Message object and
          returns 0 or 1 depending on whether the message matches
          that element of the filter.
        Don't print an error about loading subs if there is no
          .zephyr.subs
        Do the initial zephyr_buddy_check when pseduologin set to true.
        Updated man page
        
2.1.2
        removed unused filter_depth variable
        Fixed memory bug on receiving pings
        
2.1.1
        Filters of filters now work.
        Removed the "possibly not readable" part of the config parsing
          error
        In the sepbar, reverse video the view name when it's not set to
          view_home (as opposed to the static 'all').
        The '!' key (bound to 'view -r') now creates a negative version of
          the current view and switches to it.  i.e. "show me all the
          messages that are not these"
        Added the 'ignorelogins' variable
        Log when outgoing personal message fails
        Removed file descriptor from sigpipe catcher printer just for now,
          since the field does not exist on OSX
        Added an ifndef for socklen_t in libfaim/ft.c
        Added the 'aim search' command.  The popup on callback may be
          dangerous, should switch to an admin msg for results, or add a
          new event queue
        First pass at AIM away messages.  It is a little different from
          what most clients seem to do, in that an away reply is sent for
          each message received.  Most clients only reply to the first one
          per away-session.
        Now have a set of 'aaway' commands and variables just like the
          'zaway' ones (except that changing the 'aaway' variable talks to
          the server)
        The new 'away' command does everything for both AIM *and* zephyr.
          There is a known funkiness here, where if you turn one away on,
          and then use 'away' (or 'A') to toggle, you will turn on off and
          the other on.  Just leaving it for now.  Should do better in the
          next patch.
        The 'A' key is bound to 'away'
        Status bar can now read AWAY, Z-AWAY or A-AWAY.
        Changed C-n to scroll down just a line in popless
        If the config exists but is not readable, print an error before
          exiting
        Only print forced AIM logout message once.
        Don't bind F1 to help in edit context
        Fix bug in 'getsubs' with no tickets
        New code for getting users from .anyfile
        Added the 'pseudologins' variable, and code to do it
        new attributes 'pseudo' 'logintty' and 'loginhost'
        Don't print extra new lines in popless_file
        New zephyr_get_field function
        
2.0.14
        Fixed missing word in startup message
        Better 'status' command
        Use '+' for popwin corners when 'fancylines' is off
        Allow TERMINFO to be overridden in the envrionment
        Command line arg -D turns on debugging and deletes previous
          debugging file
        Do ~ expansion in 'dump' command.
        Current directory added to 'status' command
        Massive changes to libfaim and aim
        
2.0.13
        Changed startup message for new mailing list
        blist now prints AIM info even if .anyone is unreadable
        Catch SIGPIPE and print an error rather than crashing.
                [It's possible that this may have some portability 
                issues under Solaris and we may need to add some 
                configure stuff around SA_SIGINFO...]
        Handle the case in aim_bstream_send where aim_send returns -1,
                although there is likely an underlying problem here
                that would lead to this case.
        Print the username on aim login failure, not something random like
                the password.  ;)
        Un-word-wrap text when sending AIM messages.
        Replace the main loop continue in the keyboard handler with an else.
        
2.0.12
        Command history now doesn't allow the last entry
           to be repeated
        If format_msg returns "" print "<unformatted message>"
        Better align oneline admin and loopback messages
        Print an admin message indicating when subscriptions can
           not be loaded on startup
        Set aim_ignorelogin_timer to 15 by default
        Admin message on login/logout of AIM
        Fixed double quoting in smartzpunt
        Added timestamp to login/logout messages
        Fixed replies to loopback messages
        Fixed smartnarrow on classes/instances with spaces
        Added the 'loggingdirection' variable
        All loopback messages log to 'loopback' now
        Print an error message if trying an invalid color for a filter
        Fixed bug causing > not to go to end of editwin every time
        
2.0.11
        Updated basic help
        Display CC: in outgoing CC messages
        More AIM logout detection
        Don't proclaim "interfaces changed" on first build.
        Added the 'loopback' message type
        Added the 'loopwrite' command
        Added a timestamp to the default style
        Zpunt now works with weird regex characters
        Smart filters now work with weird regex characters
        
2.0.10
        Allow 'hostname' in filters.
        Fixed bug in reporting when no one is subbed to a class
        Added an extral newline in logging incoming zephyrs
        An admin message is displayed when you are logged out of AIM

2.0.9
        Added the 'fancylines' variable.
        Added the 'show startup' command.
        Added feature for capturing stderr messages
           from commands and displaying them in the errors buffer.
        Create an admin message explaning that a zephyr couldn't
           be sent
        Better reporting of perl errors (both into the errqueue
                and also clearing the error after displaying it).
        Allow default_style to be specified in config.
        Added errqueue
        Added command "show errors"
        Fixed bug removing newlines in backup files

        New libfaim
        Added the 'source' command.
        Make sure that a newline is always at the end of messages
                returned by perl style formatting functions.
        Add owl::login and owl::auth to legacy variables populated for format_msg.
        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
        Add base methods for login_host and login_tty 
                and others that return undef.
        New API for perl message formatting functions.  
                Legacy variables are still supported for owl::format_msg
                and owl::receive_msg, but these functions are now also 
                passed an owl::Message object which contains methods
                for accessing the contents of the message.  See perlwrap.pm 
                (and docs TBD) for the available methods.
                *** WARNING:  The exact API for owl::Message has
                *** not yet stabilized.
        Added "style" command for creating new styles.
                Usage:  style <name> perl <function_name>
        Added support for "show styles".  Changed global style table
                from list to dictionary.
        Changed AIM password prompt from "Password:" to "AIM Password:".
        Messages are reformatted after a window resize to allow styles
                to take into account the width of the window.
        When perl throws an error, the message is put in the msgwin
                if possible.
        Added perl functions for:       
                owl::getcurmsg() -- returns an owl::Message object for
                                    the active message
                                    in the current view.
                owl::getnumcols() -- returns the column width of the window
                owl::zephyr_getrealm() -- returns the zephyr realm
                owl::zephyr_getsender() -- returns the zephyr sender
        Made owl::COMMAND("foo"); be syntactic sugar for 
                owl::command("COMMAND foo");
        Added perlwrap.pm to contain perl code to be compiled into 
                the binary.  This is transformed into perlwrap.c by
                encapsulate.pl.
        Renamed readconfig.c to perlconfig.c and changed variables accordingly.

           owl_message_is_private
        The message object now uses a list of attributes internally, in
          prep. for supporting new messaging protocols
        owl_function_info now uses fmtext instead of one staticly sized
          buffer
        in owl_message_get_cc() require that the colon be present after
          cc.
        Added some defenses against resize crashes, and put in debug
          messages if they're encountered
        In filters 'true' and 'false' are now valid tokens.
        The 'all' filter has been redefinied to be 'true' and there is a
          'none' filter defined as 'false'
        Fixed bug in 'unsub' command that could cause file corruption
        In the zlist function, give a more detailed error message if
          the file cannot be opened.
        Renamed old instances of zsig_exec in the code to zsigproc
        Don't print the stderr from zsigproc
        Added a 'loadloginsubs' command to load login subscriptions from a
          file

          mode
        added the 'alert_filter' variable, defaults to 'none'.
        added the 'alert_action' variable, which is an owl command that
          will be executed when new messages arive that match the
          alert_filter
        added the 'term' command which takes the 'raise' and 'deiconify'
          options.  It assumes xterm for now.
        only 'make distclean' will nuke core and ~ files now
        fixes to owl_function_do_newmsgproc from Stephen
        converted functions.c to new code style, which I'm giving a shot
        Makefile.in: define DATADIR, for default owlconf.
        Makefile.in: provide "all" and "install" rules.
        configure.in: try also libdes and libkrb4, for people using heimdal
        configure.in: see if des_ecb_encrypt is already prototyped.
        configure.in: minor changes to work with new autoconf without needing acconfig.h.
        configure.in: find the install program.
        configure.in: test for use_default_colors since some versions of
          solaris don't have it, so we can at least compile something
          vaguely working there.
        keypress.c: ifdefs for keys not defined on at least some solarises.
        owl.c: don't call use_default_colors if we don't have it
        readconfig.c: added *commented out* code to try to find a
          system-default owlconf if the user doesn't have one.  Have to
          ponder if I want this
        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
          des.h.
        zcrypt.c: include owl.h so we get the configure-generated config.h

        Remove some ancient stuff from zcrypt.c
        General cleanup to Makefile.in
        CTRL and META are now OWL_CTRL and OWL_META.  OWL_CTRL moved to
          keypress.c
        do_encrypt declaired static
        if we don't have des functions, do not try to build in zcrypt
        kill the newmsgproc function on exit
        Added libfaim
        Added basic AIM support, including the "aimlogin", "aimwrite" and
           "aimlogout" commands

        The 'alist' command prints a list of aim buddies logged in
        The 'blist' command prints users from all protocols
        The 'l' key is now bound to 'blist' instead of 'zlist'
        Started work on 'addbuddy' and 'delbuddy' command but they DO NOT
          WORK yet
        Removed a bit of faim code that allowed commands to be executed.
        The 'B' key is now bound to 'alist'
        Added the 'startup' and 'unstartup' commands
        The $HOME/.owl directory is created on startup if it does not exist
        Added the 'aim_ingorelogin_timer' variable

           also prints all message attributes
        AIM logging (both in and out) now works
        Disabled 'addbuddy' and 'delbuddy' for aim since it doesn't work yet
        Hacked the Perl build stuff not to link with iconv
        
1.2.8
        Class pings are displayed differently now
        Updated owlconf.simple example to format outgoing messages.
        
1.2.7
        Outgoing messages now go through the config for formatting
        Zaway now makes an outgoing message, instead of an admin message
        The 'zlocate' command can now handle multiple users
        The simple user format for "To:" is in effect again
        Prettyed up the zwrite line for using 'reply' on a zaway

        Started implementing zcrypt command
        More updates to the intro doc
        
1.2.6
        Started adding code for newmsgproc.  It doesn't fully work yet!
          Don't use it.
        Added search, '/' and '?' to basic help.
        Will attempt to keep the current message as close as possible
             to the previous current message after an expunge.
        "set <variable>" and "unset <variable>" now work for boolean variables.
        Fixed a bug in owl_function_calculate_topmsg_normal that caused a
          segfault
        Fixed some typos in the intro doc
        Removed old zlog functions from zephyr.c
        Implemented the dump command
        New startup message
        
1.2.5
        Patch to fix memory bug in replying to CC messages
        If we're on Athena and have static krb (or other) libraries, use
          them
        Added "athstatic" program to the release, which handles the above
        Cast to an int for isspace, to make gcc -Wall quiet
        Added 'zlist' and 'l' to basic help.
        
1.2.4
        'zlog in' will now take an optional thrid argument to set the
             'tty' variable before setting the zlocation
        There is now a 'zlist' command that acts like 'znol -l'
        'l' is bound to 'zlist'
        Fixed memory leak uninitialzed memory read in fmtext
        viewwin will now say "End" instead of "More" when at the end
        Added a debugging message indicating the result of topmsg
          calculations
        You can now use %me% in filters
        The built-in personal filter is updated to do so
        Fixed a bug in moving the pointer after an expunge
        Fixed up the normal scrolling code.  Now it should always
          land on a message, but it's still not optimal.
        Added the variable 'smartstrip' which will strip kerberos
          instances out for the 'reply' command.
        Added -R/usr/athena/lib to the build for Athena
        Started updating the intro document
        Small changes to help / about
        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
          update .zephyr.subs by default.  If either is given the '-t'
          (for "temporary") option the .zephyr.subs will not be updated
        Turned off beeping for hitting the top or bottom of the list of
          messages
        Made daemon.webzephyr a special case for smartstrip
        Added 'out' as a default filter for outgoing messages
        
1.2.3
        Added filters "ping", "auto" and "login" by default.
        Added "body" as a valid field to match on in a filter.
        Temporary fix to bug where C-SPACE would cause the key handler to
             lock up.
        Messages now have a direciton (in, out or none).  Filters can
             match on this direction
        Outbound messages are no longer type 'admin' but are of the
             appropriate message type (i.e. 'zephyr') and are direction
             'out'.
        Smartnarrow now works on outgoing messages
        'info' updated to show more information for admin and outgoing
             messages
        Renamed pretty_sender to short_zuser and renamed long_sender to
             long_zuser
        Moved zsig generation to the zwrite object
        Print the zsig used for outgoing messages
        The tty variable now controls the zephyr location tty name
        
1.2.2
        Added the 'search' command.
        '/' is a keybinding for 'search'
        '?' is a keybinding for 'search -r'
        Fixed stristr, which was completely broken
        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
             and put it in functions.c
        Attempts to stay near the current message when switching views.
             When switching from an empty view to one we've previously
             been in, the new current message position will attempt
             to be close to the current position from the last 
             time we visited that view.
        Fixed bug in readconfig.c that prevented building under perl 5.005.
        Switched "C-x C-x" to only "startcommand quit"
        'getsubs' prints closer to the order you sub in.
        Modified the behavior of last so that "> >" will clear the screen.
        The new behavior of last is:
              Moves the pointer to the last message in the view.
              If we are already at the last message in the view,
              blanks the screen and moves just past the end of the view
              so that new messages will appear starting at the top
              of the screen.
        Fixed a typo in the help for smartzpunt.
        Fixed functions to handle curmsg being past the end of the view.

1.2.1
        New framework for command handling.
        New framework for keymap handling.
        Added commands for everything that is bound 
             to a key (do 'show commands' to get the full list).
        Added 'multi' and '(' commands to allow multiple commands
             to be specified on a line.              
        Added user keybindings with bindkey command.
        Added command aliases (eg, "alias foo bar").
        Added undelete command that parallels the delete command.
        Added additional options to delete command.
        The reply command now takes arguments.
        Added 'edit:insert-text' command.
        Added 'show zpunts' to show active punt filters.
        Added 'show variable <name>' and 'show variables'.
        Added 'show command <name>' and 'show commands'.
        Added 'show keymap <name>' and 'show keymaps'.
        Added 'M-u' to undelete all messages in current view.
        Fixed dotsend so that the zephyr will still send if there
             is whitespace after the dot but not on the same line.
             This should resolve an issue where dotsend wouldn't work
             if you'd gone up and edited a zephyr.
        Bug in page down fixed
        C-t will transpose characters
        Fix the scrolling bug where we would sometimes fail to scroll
             the screen down, leaving the current message off 
             the bottom of the screen.
        Refixed 'login or login' typo in help
        Fixed M-u description
        Removed 'first' and 'last' from basic command help
        Added M-N to basic key help
        Added M-D, M-u to basic key help
        Fixed a quoting problem in configure.in
        Changed top of help to use 'show' instead of M-x
        Fixed a bug in the summary field for user-created aliases
        Added "reply zaway" which sends a zaway response to the current msg.
        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
        Some buffer overruns fixed
        Variables now have a summary and a long description.
                Only the summary is shown with help.
                The long description is shown with "show variable foo".
        Added a 'scrollmode' variable which determines how the screen
             will scroll as the cursor moves.  The default behaves
             identically to previous versions of owl.
             The following modes are supported:
             normal      - This is the owl default.  Scrolling happens
                           when it needs to, and an attempt is made to
                           keep the current message roughly near
                           the middle of the screen.  (default)
             top         - The current message will always be the
                           the top message displayed.
             neartop     - The current message will be one down
                           from the top message displayed,
                           where possible.
             center      - An attempt is made to keep the current
                           message near the center of the screen.
             paged       - The top message displayed only changes
                           when user moves the cursor to the top
                           or bottom of the screen.  When it moves,
                           the screen will be paged up or down and
                           the cursor will be near the top or
                           the bottom.
             pagedcenter - The top message displayed only changes
                           when user moves the cursor to the top
                           or bottom of the screen.  When it moves,
                           the screen will be paged up or down and
                           the cursor will be near the center.
        Added owl_sprintf which returns the formatted string, or NULL.
                The caller must free this string.
                This will allocate enough memory and thus 
                avoid potential some buffer overrun situations.
        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
                message as having been sent.)
        The "Not logged in or subscribing to messages" error 
                now includes the name of the recipient.
        The "disable-ctrl-d" variable may also be set to "middle"
                which will result in ctrl-d only sending at the 
                end of the message.  This is now the default.
                This also added a command "editmulti:done-or-delete".
        Fixed a bug in the "reply -e" command.
        Always clear the command buffer before executing the command.
                (So that interactive commands can sanely do start-command.)
        Fixed preservation of e->dotsend across owl_editwin_clear().
        Added history for multiline edit windows (eg, for zephyr composition).
                The M-n and M-p keys will cycle through the history ring.
                In particular, it is now possible to edit the command line
                of a zephyr being composed:  C-c it and restart it 
                and then M-p to get the aborted composition back.
        Added owl::send_zwrite(command, message) to the perl glue
                to allow for the direct sending of multi-line messages.
                For example:  owl::send_zwrite("-c foo -i bar", "hello"); 
        Changed owl_fmtext_print_plain to return an alloc'd string to 
                avoid buffer overrun risks.
        Added owl::ztext_stylestrip("...") function to perlglue 
                 which returns the ztext with formatting stripped out.
        Added colorztext variable which can be used to disable @color()
                 strings arriving in messages after it is set.
                 (Currently, changing its value won't reformat messages).
        Outgoing zephyr logging now obeys the logpath variable.
        The '~' character in logpath and classlogpath now gets
                 replaced with the user's home directory.
        Added simple implementation of smartnarrow-to-admin that
                 creates a "type-admin" autofilter.
                 This was done mostly so that M-C-n and M-C-p do something
                 sane on admin messages.
        Added opera to the allowed options to the webbrowser variable.
        Fixed some buffer overruns in the "reply" command.
        When repying to "all" on a message that begins with "CC:" (eg, sent 
                 with "zwrite -C", the reply line will be constructed
                 from the sender and the usernames on the CC: line
                 of the message being replied to.
        There is no such thing as C-R, so left C-r as it is but added:
                 M-r --- edit reply to all
                 M-R --- edit reply to sender
        Added RCS Id strings to all files.
        'show keymaps' shows details of all keymaps after summary list.
        Added --no-move option to delete command.
                In particular, delete-and-always-move-down may now
                be implemented with 
                '( delete --no-move ; next --skip-deleted )'.
        Folded the nextmsg and prevmsg commands and functions together into 
                one command which takes arguments.
                Added '--filter <name>' option (eg, for next_personal),
                '--skip-deleted' option, and
                '--last-if-none'/'--first-if-none' options.
                Help updated accordingly.  
                In particular, the 'personal' filter is now used 
                for 'next personal'.  
                Added --smart-filter and --smart-filter-instance options 
                to the next and prev commands.
        Updated examples/owlconf.erik with the above.
        Made owl_function_fast*filt return a string and not do the 
                narrowing, to make it more general.
        Added a smartfilter command that creates a filter
                based on the current message and returns the name
                of the filter.
        Added M-C-n and M-C-p keybindings to "move to next message 
                matching current" and "move to previous message 
                matching current"
        Added variables edit:maxfillcols and edit:maxwrapcols which 
                will limit how wide editing paragraphs may get before
                they get wrapped.  This is a max and may be narrower
                depending on the current size of the window.
                If 0, the max is unlimited.  Default is 70 columns for
                edit:maxfillcols and unlimited for edit:maxwrapcols.
        Added smartzpunt command with key binding of "C-x k".
                This starts a zpunt command filled in with 
                the proposed zpunt.
        Fixed a memory reference bug in delete and undelete commands.
        Added support for perl to call directly back into owl.
        Changed the implementation of owl::command("...") to immediately
                call back into owl.  This allows perl to get the return
                value of strings returned by owl commands.
        Added the getview command which returns the name of the current 
                view's filter.

                and to not mess up spaces.  exec also returns a string
                of the output now.
        Integrated changes from 1.1.3, and added docs for "zlocate -d"
                and new show commands.
        Show with arguments produces help on show.
        Fix a bug in readconfig caught by efence (where we'd try to read before 
                the beginning of a string if it was empty).
        The perl command doesn't do makemsg directly, but instead
             returns the string and it will get printed if it 
             was run interactively.

              cases where they were used to owl_is_* 
        Changes to owlconf.erik to use some new features.
        Increased the size of the help buffer (as it 
              was overflowing and truncating the help message).

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

              and the owl_dict type.
              These include regression tests.
        Overhaul/rewrite of variable handling.  Variables are now managed
              in an owl_vardict (in g.vars) which contains a dictionary
              of owl_variable's.  Each owl_variable has dispatch functions
              for validating values, setting it and getting it,
              and for setting it to and from string values.
              The variable.c file contains the list of variables.
              Stubs for the owl_global_<varname>_get functions and friends
              are generated from variable.c by stubgen.pl.
              The help.c messages for variables now calls into variable.c
              so all information about most variables is in one place.   
        Cleaned out code from global.c and command.c that was made obselete
              by variable overhaul.
        The set command now takes a -q option to not log a message.
        Fixed a bug where set and print with no arguments would
              print "Undefined variable" in addition 
              to running owl_function_printallvars.
        debug is now a variable that can be turned on and off.
        Fixed mail,inbox message parsing in examples/owlconf.erik
        Made zaway_msg and zaway_msg_default into variables 
        Changed owl_function_makemsg and owl_function_debugmsg 
               to use varargs (ie, so they can now take a format
               string with args).
        Don't allow " and \ characters in URLs with the "w" command.
        Removed lots of build warnings.
        Popwins are wider by default so help messages fit better.
        Added an atokenize_free function.

        Added pageup and pagedown to viewwin

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