Add the branch number to cherry pick commits?

I like having the '[X.Y]' prefixes in cherry pick commit messages, so I went exploring to figure out how we could add them automatically here.

As far as I can tell, the best available option seems to be a combination of git commit --amend -m and http://stackoverflow.com/questions/7293008/how-to-read-last-commit-comment which would involve doing:

git log -1 --pretty=%B

to get the full text of the current commit message, prepending the appropriate "[X.Y] " header, and then writing it back into the cherry-pick commit with git commit --amend -m.

Is that a change you might be interested in including if I put together a PR?

The other interesting question here is whether or not to leave the original PR number in the commit summary (if it's present). If we do, it has the nice property of automatically mentioning the backport PR on the original PR page.

Perhaps this can be discussed in the core-workflow repo :) (Once I figured out how to move the script there)

So I imported the script to core-workflow (not sure if I did it correctly or not..)

Please re-create these issues there :)
Thanks.
