[PATCH] format-patch: autonumber by default

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

format-patch is often used for multiple patches at once when sending a
patchset, in which case we want to number the patches; on the other
hand, single-patches are not usually expected to be numbered.

The typical behavior expected by format-patch is therefore the one
obtained by enabling autonumber, which should thus be the default.

Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch. For users that want to
change the default behavior we provide a 'noauto' option for the
format.numbering config key.
