OK.  So it is more like "range-diff is supposed to show comparison
of pairs of patches; if format-patch shows one set of notes after
three-dash lines in its output, range-diff invoked by format-patch
to compare its patches with another set of patches should also be
comparing patches generated with the same set of notes".  That makes
sense to me.

Yup, I think I already have a fix-up patch mixed in your series in
the integration result I pushed out last night.

Yeah, that is much better than "other" (where it is unclear what are
the "primary" things that "others" are in contrast).

Thanks.
