the current on-disk file servers do follow this rule, but i don't see it
mentioned in remove(5) and at least nupas, if not the original, will
allow a rm of a message directory, with the expected sematics of
removing the message.  aoe(3) allows target directories to be
removed with rm.

if a sentence were added to remove(5), it might be "removing non-empty
directories may be disallowed by the file server."  i'm not sure that clarifies
things, though.
