When a line begins with `!` and there's no `do_shell` method defined, `parsecmd` returns `None` as the `cmd`, which incorrectly leads to `None` being concatenated to `complete_` and triggering a `TypeError`. Instead, recognize `None` as a sentinel that means we should call `completedefault`, as an empty string already is.

Actually, let me close this and open a new issue for it, since this probably deserves a real news entry unrelated to PDB... |

You can just change the gh issue number. |
