ZSH/nxterm bug

[Bitt Faulk <bitt@xxxxxxx>]

I have a bug with zsh under nxterm not setting $LINES.  nxterm is a patched
xterm upon which I will expand in a minute.

When resizing the nxterm, zsh 3.0.5 fails to set $LINES to the new size of the
window.  It does receive a SIGWINCH.  It also works properly when using the
standard distributed xterm.  bash and tcsh work properly under nxterm, at least
as far as setting $LINES.  The bug is repeatable when started with -f.

This is under Solaris 2.5.1 using X11R6.3.

nxterm is one of the many color xterms that have been patched from the standard,
specifically one that is distributed with RedHat Linux.  I liked it, so I
compiled it from the source in xterm-color-1.1-6.src.rpm.  I applied all of the
patches that come in the rpm to the source and it compiled without any changes. 
I can supply the source in a more standard form if you need.

Here is a little system trace of zsh under each term:

I hope that you haven't listed this somewhere already.  I'd hate to be a spammer.

I do not subscribe to this list, so I'd appreciate a direct reply if you have

Thanks for the shell.
