It's the got-to setup for those of us using gmail & send-email. In
git-ml.git:

    $ git ls-files | wc -l
    371333
    $ git grep -l '^\s+by smtp.gmail.com with ESMTPSA id ' | wc -l
    35326

Roughly 1/2 of those are patches:

    $ git grep --no-line-number -h -C30 '^\s+by smtp.gmail.com with ESMTPSA id ' |grep "^Subject: \[" | wc -l
