* Blacken .py files in blib2to3 This is in preparation for adding type annotations to blib2to3 in order to compiling it with mypyc (#1009, which I can rebase on top of this). To enforce that it stays blackened, I just cargo-culted the existing test code used for validating formatting. It feels pretty clunky now, though, so I can abstract the common logic out into a helper if that seems better. (But error messages might be less clear then?) * Tidy up the tests
