[PATCH v2 0/2] format-patch: Transition the default to --from to avoid spoofed mails

[Josh Triplett <josh@joshtriplett.org>]

As discussed, this patch series allows transitioning the default
behavior of format-patch to --from, to avoid spoofing mails when
formatting commits not written by the user.

The first patch introduces the format.from option to set the default
value of format-patch --from.  This patch doesn't change the default
behavior of format-patch, so it can go in without any transition.

The second patch changes the default to --from.  If you'd like to delay
this patch for a release and mention the planned change in the release
notes, let me know and I'll provide text for the release notes; if you
don't think this needs a transition period, you can go ahead and apply
the second patch.

v2: Unify the various places setting from into a single helper function.
