Bug#354293: document uxterm -e su workarounds on uxterm man page

[Dan Jacobson <jidanni@jidanni.org>]

Package: xterm
Version: 6.8.2.dfsg.1-11
Severity: minor

I can do
$ xterm -e su
fine, but
$ uxterm -e su
just seems to be like
$ uxterm -e cat
OK, maybe on the uxterm man page, say to try,
$ xterm -u8 -e su
which I figured out from doing pstree and man luit.

Maybe note on the uxterm man page that people wanting to use su should
try that.

P.S., add a comment in /usr/X11R6/bin/uxterm
on what
locale=`(LC_ALL=C LC_CTYPE=C LANG=C locale >/dev/null) 2>&1`
is supposed to do.  Is it like just plain "locale="?
This will, by the way, screw up if one does
$ sh -x /usr/X11R6/bin/uxterm
