Cool. I didn't know that you could cherry-pick a range of commits like that. > I'll switch to a github repo soon for pulls to work. Yes, you should definitely do that, because we probably won't end up reviewing anything unless it's submitted as a pull request (it's not that we don't want to, it's just that it's too much work otherwise).
