Subject: 28.0.50; Dired asks if buffer "" should be deleted with ls flag -p

1. emacs -Q
2. (setq dired-listing-switches "-Alhp") ;; the -p prints dirs as foo/,
                                         ;; i.e., with trailing /.
3. M-x dired RET ~ RET
4. Visit directory ~/foobar in dired
5. Delete ~/foobar directory in dired
6. Dired asks: "Kill Dired buffer of , too?" where it should ask if the
   buffer of foobar should be killed.

The reason is that with the -p flag to ls which prints directories with
trailing slash, `dired-clean-up-after-deletion' is called with filename
FN "/home/foo/foobar/" and then (file-name-nondirectory
"/home/foo/foobar/") returns "".

Without the -p flag, it would be called with "/home/foo/foobar" where
(file-name-nondirectory "/home/foo/foobar") => "foobar".
