push: avoid rebasing when we know there are no conflicts When pushing multiple commits, push would do one rebase per commit. This changes it track the files that have been changed as part of the push and only perform a rebase if the commit touches a file that has been changed previously. On our repo, push used to take 25 seconds per commit. With this change it takes closer to 10 seconds per commit (if there are no conflicts).
