Well, the problem, obviously, is that we are currently using
git-format-patch(1)-style patches for single commits. There are three
possible solutions that come into my mind:
1. Use a plain diff for multiple patches (like `git diff HEAD~10..`).
2. Create a patch for a squash commit (like `git merge --squash`
followed by `git format-patch`). Basically what John suggested above.
3. Create a bunch of `git am` compatible patches (like `git format-patch
--stdout HEAD~10..`).
I personally think that it might be best to create a new parameter (or
an entirely new URL) to switch between creating plain diffs (see 1) and
git-format-patch(1)-like patches (see 3). That way, we would be able to
provide both patches that mirror exactly what is in the repos and simple
patches that summarize a couple of commits.
