I'm sorry, I don't have experience with bitbucket...
I’m not sure, but I think there’s supposed to be a way to tell Bitbucket to change the set of commits you’re offering in a pull request. (Just trying to help!)
Thanks! I changed the setup.py file as you suggested to me :).
I have no setup/knowledge to test this, so I will take your word for it. At least it doesn't seem to break anything in the extension itself ;-)
