[PATCH] Add commit.status, --status, and --no-status

["James P. Howard, II" <jh@jameshoward.us>]

This commit provides support for commit.status, --status, and
--no-status, which control whether or not the git status information
is included in the commit message template when using an editor to
prepare the commit message.  It does not affect the effects of a
user's commit.template settings.
