That is the only sensible thing to do for Signed-off-by footers.

You can make it arbitrarily more complex.  A sends with sign-off, B
tweaks and tests *that* version and forwards with sign-off, A
further tweaks, which may invalidate the earlier tests, so A asks B
to retest and then forward it to Linus when everything checks out.

What should the end result look like?

	SoB: A
	SoB: B
        Tested-by: B
        SoB: A
        Tested-by: B
	SoB: B

perhaps?

This kind of complication is mostly up to the policies of the
projects that are users of Git, and not something we as the Git
project want to set in stone inside "git am" implementation.

Perhaps consult what has been discussed on Christian's "trailer"
series in the list archive and then think about how to integrate /
make use of it inside "am"?
