Since black.py is not marked as executable, the shebang in black.py serves
no purpose. black should be invoked through its entry point any way.
token.py is an internal module without a __name__ == '__main__' block or
other executable code. It contains just list of constants and small
helper functions.

This support isn't *exactly* right per PEP 3131 as the regex engine is a bit
too limited for that and I didn't want to spend time on Other_ID_Start and
Other_ID_Continue unless they're actually needed.
Hopefully this doesn't slow it down too much.
