TODO AND FIX-BUG LIST for ICBM
------------------------------

Implement scrolling the read window back to view previous messages
(use PgUp/PgDn?)  This one seems to be a real bitch.
(Note:  The enhanced /replay command can be used as a workaround
for this.)

There's a nasty bug in cursor positioning when editing an input
line that causes the input window to scroll.  It needs fixing,
but first I need to figure out why it's happening.
