Subject: [PATCH 1/2] refs.c: add resolve_ref_submodule()
Date: Wed,  8 Feb 2017 18:31:43 +0700	[thread overview]
Message-ID: <20170208113144.8201-2-pclouds@gmail.com> (raw)
In-Reply-To: <20170208113144.8201-1-pclouds@gmail.com>

This is basically the extended version of resolve_gitlink_ref() where we
have access to more info from the underlying resolve_ref_recursively() call.
