Great - thanks for the clean patch.

That seems reasonable from what I know, though I've not been following
the two projects closely recently.

I don't think the compatibility break with Python 2 is a big problem
(in particular, u"english" compares equal to "english" under Python 2,
which will avoid many problems).  I'm bumping the version number to
'1.2.0' instead of to '1.1.1' as you did, though, to reflect this
incompatibility.

I think that's fine, too.

Great - I've applied the patch, and will release the new version to
the python package index shortly.
