Hi, thanks for the detailed reply :-)

OK, that resolves my Q about git commit.

But should not git format-patch & send-email detect an extant in-body
From or Subject header?

Suppose I need to forward a patchset and cannot amend the commits in
git? Or that a patchset author is not the copyright holder, whom I
want to be logged as the author upstream?

There is a workaround: delete the From headers in the patches, but I
was looking for a command-line option or alternate default behavior
:-)
