Not entirely surprising.  I wondered about that but tried it with a couple
of apps before posting and they seemed to be responding to the change in
size.  I didn't actually test whether they were receiving WINCH, though.

The below should help, but someone will have to commit it for me, because
the computer with my sourceforge ssh keys suffered a video chip meltdown
yesterday and I haven't had a chance to repair it or pull the key file from
backup yet.  For the same reason, I'm composing this in gmail, so I hope
the patch has not been mangled.

Something similar may also be needed in the zpty and clone modules.  (Has
anyone ever used the clone module for anything?)
