But you need to distinguish between cases 2 and 3: you've suggested returning
EACCES whenever the user does not have permission to delete the directory, but
Richard says he needs to ONLY return EACCES when the user does not have
permission to delete the directory AND the directory is truly empty. If the
directory is not empty, he returns a different error, so clearly he needs to
know if the directory is empty or not.
