The code looks vaguely correct. I don't remember the behaviour of
using get_style_guide without providing a list of default config files
though (I doubt it affects this though).

nose may not support this usecase.

So if you do `python setup.py tests -s` then the errors will all be
printed, correct? I suspect this is something to do with how flake8
defers printing and how nosetests expects to receive data on stdout.
I'm not sure flake8 wants to support nose like this.
