[PATCH 07/19] commit: add repository argument to lookup_commit_graft




From: Jonathan Nieder <jrnieder@xxxxxxxxx>

Add a repository argument to allow callers of lookup_commit_graft 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.

The included coccinelle semantic patch will adapt any new callers in
the diff produced by `make coccicheck`.
