Subject: [PATCH 10/19] shallow: add repository argument to check_shallow_file_for_update
Date:   Thu, 17 May 2018 15:51:45 -0700
Message-Id: <20180517225154.9200-11-sbeller@google.com>
In-Reply-To: <20180517225154.9200-1-sbeller@google.com>

Sender: git-owner@vger.kernel.org
Precedence: bulk

Add a repository argument to allow callers of check_shallow_file_for_update
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.
