1. Start emacs -Q 2. C-x C-f 3. Delete the entire minibuffer input 4. Enter /etc//s 5. Press ?You will see candidates like etc//sbin/. The candidates can get even stranger. If you enter /etc//etc//etc/s then you will get candidates like etc//etc//etc//sbin/. I can reproduce this bug on 27 and 29. I haven't tried 28, but the issue should exist there too.I don't think it's a bug (look at what the minibuffer shows in those cases), perhaps just a minor aesthetic thing, but I'm adding Stefan in case he has comments.He's right, that's a bug. *Completions* normally only shows the list of matching files in the final directory, so complete filenames. It's even more true here where the "excess" is not even really part of the file name since it'll be stripped away by `substitute-in-file-name`.E.g. if you replace "/etc//s" with "~//s" in the example, we show the correct list.
It's a bug indeed, but a very old one, it's also present in Emacs 24-25-26-27-28.
