You can also use a normalizer.  They make dealing with these sorts of
inter-Python formatting differences pretty easy.

Those tests could probably use Manuel's footnote support instead, but
that would add one more dependency (Manuel) that would have to be ported
to Python 3 -- and I don't have any expectation that I'll be doing that
in the near future.

I'd like for them to be unified too, but even ignoring
INTERPRET_FOOTNOTES, the two have drifted apart quite a bit.  The last
time I looked at it I stopped after spending several frustrating hours
comparing diffs and trying to get one's tests to run on the other.

Maybe you'll have more success than I did.
