Is there a way to accept them while rejecting the parent directory? If
not, I opt for ignoring those rather than having commands that fail when
used with the default parameters suggested by Emacs.

We could add "..?*" but that doesn't match directories:

oscar@qcore:~/dev/emacs/emacs$ ls ..?*
ls: cannot access ..?*: No such file or directory
oscar@qcore:~/dev/emacs/emacs$ mkdir ..foo
oscar@qcore:~/dev/emacs/emacs$ ls ..?*
oscar@qcore:~/dev/emacs/emacs$ rmdir ..foo
oscar@qcore:~/dev/emacs/emacs$ touch ..foo
oscar@qcore:~/dev/emacs/emacs$ ls ..?*
..foo


This is also puzzling to me:

oscar@qcore:~/dev/emacs/emacs$ ls .?
build         dbuild  old-emacs     ses.patch          tooltip_pos.diff
build.script  emacs   pmodes-tests  tooltip_pos2.diff
oscar@qcore:~/dev/emacs/emacs$ ls ?
ls: cannot access ?: No such file or directory
