Note: The "forwardported PRs" section includes not only the commits in this PR, but also the commits that have already been forwardported and already exist on the master branch in this repo.

This is because I'm hacking the Backporter script to use it in a way that it's not normally used.

[DilumAluthge]

Every unchecked PR needs to be manually cherry-picked. When you do the cherry-pick, do it with -x, so that the final cherry-picked commit includes that magic line of the form:

(cherry picked from commit ...fullcommithash...)

When the Backporter script sees that magic line, it will update the PR description to reflect that the PR has been forwardported.
