[python-committers] GitHub: allow Rebase and merge

[Victor Stinner]

Hi,

Would it be possible to keep "Squash and merge" button by default on
GitHub pull requests, but allow "Rebase and merge" to keep multiple
commits when they are well written. Example of such PR:
https://github.com/python/cpython/pull/489/commits

Maybe the second commit lacks bpo-xxx, but it's not a big deal. I
prefer smaller atomic commits when possible.
