Worse yet: creating backup files in /tmp would be a security hole:
some other user seeing you're currently editing /tmp/foo could create
a symlink /tmp/foo~ to some interesting place and then when you save your
file the backup could be placed at that interesting place chosen by
the attacker.
Is that equally true for any directory that others can write?
