wherefore art thou, git-applymbox? - Adding non-self signoffs

Junio, et al,
	When git-applymbox disappeared, I didn't pay much attention.  I
just learned git-am and went along.  Little did I know, there was a
trap laid.
	The ocfs2-tools.git repository is maintained by the entire ocfs2
team.  It's a "shared" style repo.  A proposed change is posted to
ocfs2-tools-devel, and when a teammate approves, they respond with a
signoff.  The author then adds the signoff to the patch and pushes to
the shared repo.
	We used to do this very easily with git-applymbox:
(from http://oss.oracle.com/osswiki/GitRepositories/ForMaintainers)

$ echo "Julie Hacker <julieh@my.site.com>" > /tmp/signoff $ git branch to-push master $ git checkout to-push $ git format-patch -C -k --stdout master..workingbranch > /tmp/changes-to-push $ git applymbox -k /tmp/changes-to-push /tmp/signoff $ git push ssh://my.server.com/path/project.git to-push:master

	The <signoff> file argument to applymbox allowed us to add the
approvers signoff to an entire series in one go.  git-am does not have
this feature.  As far as I can tell, I have to edit each patch by hand
to add the new signoff.  Is there a better way?
