Dear Maintainer,

At the moment, bash completion for commands like `chown` or `chgrp` struggles with
entities that have a backslash (`\`) in their name, i.e. those provided by winbind
for an AD domain.

The suggestions wrongly omits the second backslash needed for escaping purposes,
i.e. the raw name is inserted.

If a user fixes the bad insertion, bash completion no longer understands the
entered command and refuses to provide further completions.


Best regards,
Mindy
