It still happens the very same way.  The only thing this patch is
concerned with is that if bar (specified as bar/) does not exist yet, it
will be created as directory before doing the operation (i.e., the
rename or copy).

So basically we have those Rename/Copy semantics:

  file -> 2.txt (renames plain file no matter if 2.txt already exists)
  file -> foo   (move into foo if that's an existing dir, otherwise rename)
  file -> foo/  (move into directory foo, creating if not existing
                 and dired-create-destination-dirs is non-nil)

The first 2 are unchanged, the third one is the new one.

The above. :-)

And Rudi, please correct me if I'm wrong.  But I think I've tested quite
thoroughly.
