Couldn't it be then per-branch setting, whether to mail even commits
that aren't new to the repository or not (like I understood it is already
possible to decide per-branch whether to send mails at all)?
E.g. for GCC, I'd certainly like to see mails for all commits on the
trunk and release branches (but we don't allow merge commits on them
anyway), and for other branches (personal, vendor, devel) I think mailing
only about new commits not already in the repository would be better over
not mailing at all.
