commit 7f4e5320512ed5a2b28d740e0dc25cde52ba1876
from: Stefan Sperling <stsp@stsp.name>
date: Mon May 29 14:50:36 2023 UTC

only delete empty directories appearing in arguments to 'got rm'

Make 'got rm' keep empty directories which are not explicitly listed for
deletion. Deleting such directories is problematic in several use cases.

Avoids deleting the current working directory when the user runs "got rm *"
(pointed out by Mikhail), and avoids deletion of an empty directory "foo/"
after 'got rm foo/a foo/b' (pointed out by op@).
