Yes; I already agreed about that in response to a posting from Geoff on
Feb. 3.  The code is as it is now (and I changed it as I did in that
patch) because I didn't know about the meaning of "termok".  It would
be possible to replace all the fudging of SINGLELINEZLE and ZLE with
changes to "termok" -- at least, I think that's what PWS said at some
point.

I think "termok" is the right thing for that, too, but Peter or Geoff

I believe Geoff also said that there were some changes he needed to make
for very narrow terminals as well as very short ones.  Geoff?
