Yes in the second paragraph, I was mainly just going to expand on it
and provide a suggestion.

But I mainly wanted to point out that not having this feature means
that people do completely manual reverts. So I think we'd have less
"broken" history (message), not more as a result of this sort of
thing.

Yes this looks very good. Aside from the UI issue of someone expanding
on why they did that *inside the comment* because that's what it suggests :)

    This partially reverts commit <sha1>.

    # DESCRIBE ABOVE ...

Would probably be better.
