Hmph, can this be accompanied with a change to add a test to an
existing test script to demonstrate that the function can be called
with me set to "rebase" and results in a generic message?

This needs to be reviewed by somebody who is more familiar with the
rebase/chrry-pick/revert/sequencer codepaths so that they can give a
definitive "good--I know that we never call this function with any
other value in 'me'" and that person would not be me.

True, but that can be left to a different topic, I would think.
