Make kwfiles -u show untracked files only (like status) Remove extra documentation of -u/--unknown, as this is covered in the option help already. Like commands.status the code now zips the status flags. Add more kwfiles tests.

Make kwfiles --all show unknown files too More consistent and similar to hg status.

kwfiles --unknown instead of --untracked Use the same option name as "hg status". Retrieve option in _status(). Mark --untracked as deprecated.
