Test for a bug reported by Bernd Walter: In passthrough mode,

copying "dir/file" and then copying "dir" results in
"File on disk is not older; skipping" for the "dir" because
it was implicitly created by "dir/file."  Among other sins,
this means that "dir" ends up with the wrong permissions
and ownership.

This is actually a libarchive bug; fix is forthcoming.
