One more for the frequently asked questions....

Due to Elm's mini curses internal stuff, it doesn't know whats
on the screen, so it cannot redraw it.  It can repaint the menu,
or the list of messages, but that might not be what is on the screen.

We had planned to go to a real curses a while back, but couldn't
really get a portable set of curses routines working, so we punted it.
(too many bugs in too many manf. curses packages).

not easily.
