[bug#57646] [PATCH] etc: teams: Add regular expression support to scopes.

Hey,

Right, for now I went for the easiest solution and proposed the following
example in the documentation:

--8<---------------cut here---------------start------------->8---
$ guix shell -D guix
[env]$ git send-email $(./etc/teams.scm cc-members HEAD~2 HEAD) *.patch
--8<---------------cut here---------------end--------------->8---

> +                 ""))
>
>   I’d prefer using match:

Fixed!

Thanks,
