I just downloaded both tarballs and it looks like there were a small
number of commits in the cython.org one that weren't on PyPi. I
thought I had uploaded and then done sdist, but maybe I messed
something up with branches while doing some last tests. My bad, I've
copied the PyPi ones to cython.org. Thanks for bringing this to our
attention, we'll be more careful about this in the future.

This is what usually happens, though we should re-download to get
exactly the same file.
