Bug#714188: pdfjam doesn't respect TMPDIR, and uses /var/tmp unconditionally

[Ivan Shmakov <oneingray@gmail.com>]

Package: texlive-extra-utils
Version: 2013.20130530-1

	The current version of pdfjam(1) doesn't respect the value of
	the conventional TMPDIR environment variable and just uses
	/var/tmp unconditionally instead.  (Even though pdfjam(1)
	appears to use mktemp(1) internally, subject to one's
	availability, which implements the usual TMPDIR handling.)

	Consider, for instance:

$ nl -ba < /usr/bin/pdfjam 
     1	#!/bin/sh
     2	version=2.08
…
   170	##  Next a permitted location for temporary files on your system:
   171	##
   172	tempfileDir='/var/tmp'   ##  /var/tmp is standard on most unix systems

	My suggestion would be to change it as follows:

-tempfileDir='/var/tmp'   ##  /var/tmp is standard on most unix systems
+# tempfileDir='/var/tmp'   ##  /var/tmp is standard on most unix systems
+tempfileDir=${TMPDIR:-'/tmp'}    ##  /tmp is the default on Debian

	(The use of /tmp for the default is to match Debian's
	mktemp(1).)
