Now, I have a curiosity question.  Why this (unchanged) construct:

   test -n "$tmp" && test -d "$tmp"

and not just:   test -d "$tmp"
It is sufficient for every shell I know about.  Even some pretty old
ones.  :)

Some old shells would match an empty $tmp with "."
(I don't recall which, but did run into it).
