python3: add supported python versions to setup.py Mercurial technically can support Python 3.5 (although no lower, see its setup.py), but `evolve` probably won't because it represents more work for an underrepresented Python version. If you happen to *really* need evolve to work on Python 3 and you're reading this message, send an email to the mailing list, or contribute patches.
