It would be nice if the Shell Variables section of documentation mentions
that $TMPDIR can affect where temporary files are created, and situations
where that happens (such as when processing here-docs).  Furthermore, the
FILES section should mention that when TMPDIR is not defined, the tmpdir
search proceeds through '/tmp', '/var/tmp', '/usr/tmp', and '.', for the
first directory writable by the current user.  Bash 3.0 does not document
this anywhere, so I had to go digging through the source code to find it
(see lib/sh/tmpfile.c).
