Bug#318513: needed to use sh -x /usr/X11R6/bin/uxterm

[Dan Jacobson <jidanni@jidanni.org>]

Package: xterm
Version: 4.3.0.dfsg.1-13
Severity: normal
File: /usr/X11R6/bin/uxterm

Very interesting.
$ sh -x /usr/bin/X11/uxterm
gets me a uxterm, whereas
$ sh /usr/bin/X11/uxterm
just gets me error messages.
Adding -x changing the outcome of scripts? Uh oh.

Indeed, if I change the top line to #!/bin/sh -x
then it works if I call it directly.

Add a comment to the source to say what this does:
locale=`(LC_ALL=C LC_CTYPE=C LANG=C locale >/dev/null) 2>&1`
and how it is different than
locale=
and why the ().

Well, at least it enabled me to get a perfectly good uxterm, as I see
in the output
+ locale='++ LC_ALL=C
++ LC_CTYPE=C
++ LANG=C
++ locale'

whereas all I would have gotten otherwise is
$ uxterm
uxterm tried to use locale zh_TW.UTF-8
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

Isn't that neat. -x debugging stuff stuffed into a variable allowing
me to get an uxterm when even this won't:

$ LC_ALL=C LC_CTYPE=C LANG=C uxterm
uxterm tried to use locale en_US.UTF-8
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

$ locale -a
C
POSIX
