[PATCH v2 2/4] Add format.coverauto boolean

[Frank Terbeck <ft@bewatermyfriend.org>]

If set to true, format-patch behaves like it had been started
using the --cover-letter option.

An exception is if it is called using the --stdout option,
which disables format.coverauto, because users of --stdout
(like git-rebase.sh) usually are not interested in
cover letters at all.

If you do want it anyway, you can use:
  % git format-patch --stdout --cover-letter
