BarnOwl fails to redraw properly on some terminals

[wdc@MIT.EDU]

I should have reported this long ago.

Repeat by:

Log onto an Athena 9 system
in the default gnome terminal on screen:
add barnowl
barnowl
receive a couple screen-fulls of messages.
delete some offscreen and some onscreen messages, leaving a some on
screen.
expunge

Expected behavior:

The screen should update with all the deleted messages gone, and the
remaining messages being displayed accurately as if they were the only
messages present.

Actual behavior:

The screen contains a mix of text from current and deleted messages in an
undifferentiated mess.

Work-arounds:

1. Run owl in xterm.
2. Hit ^l after every expunge command.

Note that this problem also sometimes happens when scrolling to off-screen
messages.

Does this still happen (on any system that we care about)?
