I find it a little curious that this option can only be used with
"--from". That makes sense in a way, because this is a special case of
that feature, overriding the "are they the same" check.

But given that the use case is not to send somebody else's patch, but to
duplicate your _own_ ident in both spots, it feels funny that you must
also say "by the way, I am the sender of the email". I.e., you have to
say:

  git format-patch --from='Me [off-list ref]' --force-in-body-from

I guess it is not too bad because just "--from" will do the equivalent
thing (picking "me" from your committer ident). It just feels kind of
clunky that:

  git format-patch --force-in-body-from

will silently ignore the option.

All that said, I don't care _too_ strongly about it. I do suspect the
feature might be better placed in send-email (or possibly in addition).
If you are using send-email, then I think you're not supposed to use
"--from" with format-patch at all, and you have no way of accessing this
feature.
