commit: support commit.status, --status, and --no-status

A new configuration variable commit.status, and new command line
options --status, and --no-status 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.
