This change has obvious interactions with Dscho's d51b771d ("t3427: move the `filter-branch` invocation into the `setup` case", 2019-07-31) that is still in flight, but in a good way. There only needs a single callsite for the above helper function after that step.

I think I'll discard this step from the "move us closer to deprecate filter-branch" topic, and ask you and Dscho to work together to have it or its moral equivalent included as part of js/rebase-r-strategy topic.

Thanks.
