Oh, I got a profile from the test case for my own interest.

6615 seconds ..

some highlights that jumped out at me

    20001    0.127    0.000 6610.025    0.330 difflib.py:868(compare)

which means we're basically using ndiff, which is cubic rather than quadratic - the same performance issue the html module had.

I think we'll probably make a better tradeoff by using unified_diff instead which is quadratic.
