Subject: [PATCH 04/15] refs: move submodule slash stripping code to get_submodule_ref_store
Date: Fri, 17 Feb 2017 21:18:57 +0700	[thread overview]
Message-ID: <20170217141908.18012-5-pclouds@gmail.com> (raw)
In-Reply-To: <20170217141908.18012-1-pclouds@gmail.com>

This is a better place that will benefit all submodule callers instead
of just resolve_gitlink_ref()
