I see 'git send-email' in the above, so you'll also want to wrap with
`(,git "send-email").  Did you test that this suffices to get a fully
self-contained working patman?  Maybe you can send a v2 with patman.

You can add these 'Series-*' git trailers to your commit:

--8<---------------cut here---------------start------------->8---
Change-Id: xxxxxxx
[...]
Series-to: 66704 <at> debbugs.gnu.org
Series-version: 2
Series-changes: 2
 - Also add 'send-email' output of git to wrapper

--8<---------------cut here---------------end--------------->8---

Then to send, you simply do:

$ patman

And it'll annotate the patch for you and you don't need to remember
tracking the '--to' value.
