Subject: [PATCH 02/20] refs_read_raw_ref(): new function
Date: Mon, 20 Mar 2017 17:33:07 +0100
Message-ID: <3962e229cf0eb9daad8b5ed55b98fc9dbdd0d64a.1490026594.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1490026594.git.mhagger@alum.mit.edu>

Extract a new function from `refs_resolve_ref_unsafe()`. It will be
useful elsewhere.
