For multiple patch series, is it worthwhile to mention the "--stat"
option to include the diffstat in the cover letter?  When reading a
patch series, I find it useful to see the diffstat at a glance.

E.g. when sending the top 4 commits:

    $ git send-email -4 --cover-letter --no-chain-reply-to \
        --annotate --to=libvir at redhat.com master --stat

Maybe others here have their own preferred method to include diffstat in
cover letters.
