This is BETA code.  I *know* there is an anomalous curses bug somewhere
that I've spent tons of hours trying to track down and kill.  I was
unsuccessful.  If someone can do it, send me the patches.

The bug happens irregularly and infrequently, but you'll see how the
scrolling is messed up when it happens.  Well, the scrolling still works,
but the lines are a little messed up...only like one line.  You can hit ^L
redraw and fix it, but when it scrolls again, that same line is back that
way.  All I know is that it's right in memory, and it's being sent to
curses correctly...what curses is doing with it, I don't know.
