SuSE 9.1 weirdness resolved

[Dave Ulrick]

A while back, I reported a problem with ncurses 5.4 on my SuSE 9.1 
Professional system that prevented KEY_RESIZE from being delivered to my 
application when a konsole or xterm window was resized.  Today, I happened 
to notice that KEY_RESIZE worked correctly if I ran my app in an xterm or 
konsole directly from KDE.  Then it occurred to me that an app launched in 
that manner might not get the same environment variables as would if it 
were launched from an interactive bash shell.  Afer running a 'set' 
command in the same environment that worked for my app, I noticed that the 
LINES and COLUMNS environment variables weren't present.  With a little 
more hunting, I found a statement in /etc/bash.bashrc.local:

        export LINES COLUMNS

Now that I've removed this statement, my program receives KEY_RESIZE 
events.  Also, 'less' no longer shows a corrupted screen when run by my 
app after a window resize.

Conclusion:  _don't_ 'export' LINES or COLUMNS, lest strange things happen 
to your ncurses apps!
