Admittedly the conditional in `__sub__` is a little gross now.
I didn't add release notes as this is really just patching up a yet-to-be released item, but please let me know if I should.
Also, the test only runs on numpy >= 1.7, is that okay?

Stata requires string names, the proposed fix attempts to rename columns using
