Around 66% of qemu.git commits since v4.1.0 include a Message-Id: tag. Hooray!
Message-Id: references the patch email that a commit was merged from. This information is helpful to anyone wishing to refer back to email discussions and patch series. Please use git-am(1) -m/--message-id or set am.messageid in your git-config(1). If you use the patches tool (https://github.com/stefanha/patches) then Message-Id: is added automatically. Thanks, Stefan
