We're not the only people to run into problems with 2to3 and doctest
not working properly:

Most of our doctests still work after 2to3 and I guess we can look at
the failures on a case by case basis (and for expediency move them
into proper unit tests or remove them if they can't be tweaked to
work on both Python 2.x and 3.x).
