check-code sez:

hgext/convert/git.py:154 (bryano at 16370):
 >         return self.repo[rev.decode('hex')].data, self.modecache[(name,rev)]
 missing whitespace after ,

As check-code is run by the test-suite, it rats out folks who submit
patches without running tests.

This probably wants a ui.note("using pygit2\n") or similar so that we
can diagnose people's inevitable complaints of "I installed pygit2 but
it's still slow!"

Hopefully Patrick will give some further feedback.
