git-applymbox and git-mailinfo refer to a --mbox
option of git-format-patch. But there is no such
option AFAICT. mbox output can produced with
format-patch --stdout.
This patch only replaces --mbox with --stdout.
Some further explanation and/or format-patch
arguments (e.g. -k) might be needed.
I would agree. "Reads single mbox with one or more patches in
it, without munging the subject line" is what it really does, so
we obviously mean "--stdout -k >mbox" here.
