[RFC/PATCH 0/3] support mboxrd format

Sometimes users will copy+paste an entire mbox into a commit message, leading to bad splits when a patch is output as an email.

Unlike other mbox-family formats, mboxrd allows reversible round-tripping while avoiding bad splits for old "mboxo" readers.

I'm also considering altering the current "From ${COMMIT} Mon Sep 17 00:00:00 2001" line to something else so mailsplit (or "am") can autodetect.

Maybe:
	From ${COMMIT}@mboxrd Mon Sep 17 00:00:00 2001
?

We may also want to default to single escaping "From " in commit messages for --pretty=email to avoid corruption when somebody copy+pastes an mbox into the commit message. This is a technically incompatible change, but I think it's preferable to breaking splitting complete.

In other words, --pretty=email changes to output "mboxo" for now.

Long term (possibly git 3.0?), maybe mboxrd can become the default mail format. IMHO, it should've been since 2005.
