I honestly don't remember (probably overkill). I knew about the curscr
hack from experimentation (and because it was broken in ncurses a couple of
years ago ;-).

In any case, I'll have to come up with a workable hack for bsd curses
since I want to be able to benchmark my directory editor on different flavors
of curses. (I had a workaround for the broken touchwin that worked on the
bsd4.3 curses on Apollo, but it can't defeat the bsd4.4 bug - though there's
more than one version of _that_ - the one I've on Linux works ok, but the
one on FreeBSD as well as the one on BSDI is broken).
