[PATCH 3/5] submodule-config: add repository argument to submodule_from_{name, path}

From
Stefan Beller <sbeller@google.com>
Date
Mar 27, 2018, 21:39 UTC
Message-ID
<20180327213918.77851-4-sbeller@google.com>
In-Reply-To
<20180327213918.77851-1-sbeller@google.com>

This enables submodule_from_{name, path} to handle arbitrary repositories. All callers just pass in the_repository, a later patch will pass in other repos.
