+1.  And put it in the email (subject?).  While it’s possible to derive a count from a hash manually, better to have it in the email in the first place.  You can’t rely on order-of-email-delivery to reflect order-of-commit.

I thought we were just going to count commits on a particular branch and use the (branch name, commit count) tuple as our monotonic incrementing identifier? https://llvm.org/docs/Proposals/GitHubMove.html#on-managing-revision-numbers-with-git

     This actually what we are doing, we are listening for github commit events and
     then generating our own emails based on the data in the event.  We can format
     the emails how ever we want, and we tried to match the current SVN format exactly.
Ah great!

     Is the some other information you would like to have in the emails to show the
     ordering?
The only thing I was looking to get was to continue to have a monotonic incrementing integer for the revision instead of the git hash alone: I don't know if `git llvm` has this feature yet but this was discussed a while ago (I don't remember if we just mentioned counting the commits in the repo from the beginning or using an invocation of `git describe` or something derived).

We talked about using `git describe` for this, but this would require that we
add tags to the master branch each time the version number was bumped.  We
discussed this[1] last year, but deferred the decision, since we couldn't get
consensus on the tag name.
