And this is not an artificial limitation but there is no way that this
could conceivably work.
By Unix design, removing a file or directory basically means removing
its entry from its parent directory, so it is not an operation on the
file in the first place (or on the target directory in this case).
The parent directory is obviously needed by design, thus "." is not
something that could ever be removed (from where?).
