[PATCH 1/1] git-am: provide configuration to enable signoff by default

[Sekhar Nori <nsekhar@ti.com>]

Provide a git config option to enable --signoff a
default when using git-am. This should be handy
for maintainers who regularly apply patches from
mailing lists to send them upstream and want to
be on the sign-off path.
