Lib/unittest/main.py:233: self.pattern[0]==self.pattern[-1]:
Just a style nit, it's best to avoid backslashes wherever you can.  Here
you can do so by wrapping the whole condition in parentheses.

Also, the indentation of the continuation line looks wrong to me, but
I'm honestly not sure what "right" should be.  I seem to think PEP8 says
to indent an extra level from what the suite should be, but I haven't
looked it up again.
