I'm using `--transform` to move all the files from a subdirectory to its
parent, something like
tar cf ... '--transform-s|^foo/bar/|foo/|' ...
this works fine, except that I'm left with an entry for a directory
`foo/bar` (which remains empty, of course). I can solve this problem
with:
tar cf ... '--transform-s|^foo/bar\(/\|$\)|foo/|' ...
so the transform also applies to `foo/bar` itself, but then I end up
with two entries in the tarball for the `foo` directory.
Now, in practice it seems not to cause any problem, but I was wondering
is there was a way to remove this duplicate entry?
It also made me wonder if there'd be a way to use `--transform` in order
to *remove* (rather than rename) an entry (e.g. by renaming it to an
"impossible" name)?
