Title: Forbid adding superfiles to themselves

As reported by Dustin Skaggs, we should not add a superfile to itself.

This patch assumes names are unique and uses it to avoid superfile lookup/creation in case we'll bail out anyway.

Test added to make sure we always fail in that case. All other regressions passing.
