I see no uses of this tag yet, and I'd like to get it right. If patch
v1 was written by author A, then heavily modified and sent by author B
to produce patch v2, what should the resulting states of git-author,
and tag order be? I'm assuming it should be:

git-author: B
...
Signed-off-by: A
Co-Developed-by: A
Signed-off-by: B

It's not clear to me if git-author should instead be A, and/or
Co-Developed-by should be B...

Thanks!
