Release Status: release

Description:

    Temporary file cannot be created when using here document due to
    lack of permissions on /var/tmp.

Repeat-By:

$ cat <<EOF
> qwe
> rty
> EOF
-bash: cannot create temp file for here document: Permission denied

Fix:

    Add code in lib/sh/tmpfile.c to check that directory is writable,
    not merely that it exists.
