Actually the above is _not_ a good example for using 'origin', and why
using 'origin'; just a bit convoluted example of multiple 'origin'
headers.

If I understand correctly the point is to record those 'origin' headers
for git-revert (when 'origin'-ed commit is somewhere in the history),
and for git-cherry-pick from other long lived branch and thus require
additional option to git-cherry-pick to record 'origin' (denoting that
you this is "true" cherry-pick, and not reordering of commits and
cleaning up a history, better done with interactive rebase).

/me is playing advocatus diaboli here, 'cause I'm not that convinced
to necessity of this feature.
