Last change on this file since 486688f was 486688f, checked in by Erik Nygren <nygren@mit.edu>, 18 years ago
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. (although I'm not totally happy with how I implemented it.)
