To follow up: You can now follow up. I've added "reply" functionality,
fixing what I think was a bug in libpanel in the process. The latest
version, yet again, is in /n/sources/contrib/john/uwn.tgz. The
interactions between the reader and the writer are really bad, I need
to work on that, but I thought I'd send this first.

The possible bug was that setting up a pledit(panel, PACKE|EXPAND,
Pt(0,0), inittxt, runestrlen(inittxt), 0); would cause the writer when
replying if the message being quoted came to over 100 characters long.
Some experimentation later, I changed line 64 of libpanel/textwin.c
from
if (l>t->eloc-t->loc) {
to
if (l>=(t->eloc-t->loc)) {

which seemed to fix the problem. If it wasn't a bug and I was merely
calling the pledit function wrong, please let me know.
