Hrm, -maxdepth and -empty are not even in POSIX. Folks on GNU
platforms and BSDs (I checked NetBSD 6 and OpenBSD 5.2) should be
fine, but it makes other platforms unhappy.
What is this check used for? To avoid running "rmdir" on non-empty
ones? Saying "cleaning foo/" (or "cleaned foo/") when foo/ is
already empty is not a crime; not omitting an empty one may actually
be a better behaviour from the point of view of repeatability and
uniformity.
