From: Jonathan Nieder <jrnieder@gmail.com>

Add a repository argument to allow callers of commit_graft_pos to be more specific about which repository to handle. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time.
