path.is_empty() checks for the empty-path, not an empty directory [0]. as the check that the path is below the link_dir happens anyways in the if we can directly call std::fs::remove_dir (which is even safer than the std::fs::remove_dir_all call used in pool::remove_dir()).
the oversight seems to have been in place since the intial commit. I ran across the issue when removing many snapshots of a Debian Bookworm repository, syncing this to a medium, and still having a vast amount of empty directories left behind (as debian has one directory per package), which in turn increases the sync run-time.
