Documenting that we should not add new lines to work around SPF rewrites sounds foreboding; the intent is instead that new lines here are okay, but indicate a second problem elsewhere in our build process that we should also consider fixing at the same time, to keep the section from growing without bounds. While we have been doing that for qemu-devel for a while, we jut recently fixed that for qemu-block: https://git.linaro.org/people/pmaydell/misc-scripts.git/commit/?id=f9a317392 Mentioning DMARC alongside SPF may also help people grep for this scenario, as well as documenting the 'git config' workaround that can be used by submitters to avoid the munging issue in the first place. Note the subtlety: 'git commit' sets authorship information based on user.name and user.email (where name is usually unquoted); while 'git send-email' includes a body 'From:' line only when sendemail.from is present but differs from authorship information. Hence the use of quotes in sendemail.from (not a semantic change to email, but enough of a difference to add the body 'From:').
