I foresee git cherry potentially learning how to parse this, for example, for cases where the patch-id doesn't match due to context changes. However, I do have concerns about breaking compatibility with existing scripts. I wonder if we could add a long alias for git cherry-pick -x, say "--notate" and have "--notate=text" mean "-x" and "--notate=trailer" mean this new format. Similarly, git revert could learn such an option as well. One final thought: since our trailers seem to act as if we wrote "this commit" (has been), I wonder if we should say "Reverts" instead of "Revert" for consistency. -- brian m. carlson: Houston, Texas, US OpenPGP: https://keybase.io/bk2204
