I think he's trying to fix a bug in terms of slipshod definition of the
non-empty-directory subcases, but it would be nice to have some
clarity about that.
There is at least one other bug in that function now that I look at it:
in event of a readdir() failure, it neglects to execute closedir().
Perhaps not too significant since all existing callers will just exit()
anyway after a failure, but still ...
