I learned today that GitHub now supports multiple author info in a commit. https://help.github.com/articles/creating-a-commit-with-multiple-authors/ and https://github.com/blog/2496-commit-together-with-co-authors It can be done by adding: Co-authored-by: name <email address> as the footer of the commit message. I tested this in CPython: https://github.com/python/cpython/commit/6ea75b174da0cf824e2acc5db6b53798f5f... I suggest we start adding this where it makes sense, to give proper credit to PR authors. What I've seen is that we've only been writing "Original Patch by <someone else>". One scenario is when we convert someone else's mercurial patch to GitHub pull request. Or when someone started a patch, and another person finished it. The other scenario is with miss-islington's backport PRs. I will try to find time this week so that miss-islington or cherry_picker will add the "Co-authored-by:" automatically. Mariatta Wijaya
