Confusing status command behavior

[nadapez]

When I execute the status command tmsu status

without a path, sometimes untagged files are listed with code U, although not all untagged files.
I think the intended behavior is not to show untagged files at all when no path is given.
I understand untagged files should only be shown with tmsu status some/path or tmsu untagged ...

Now I found out that the files under tagged folders are the ones shown as untagged files if they are untagged.

This behavior should be documented.
