Last change on this file since 217a43e was 217a43e, checked in by Erik Nygren <nygren@mit.edu>, 19 years ago
Fixed a bug in the "reply -e" command. 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".
