From 0fec0822721cc18d6a62ab78da1ebf87914d4921 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [PATCH] git-ls-remote: show and optionally store remote refs.

Retrieve and list the remote refs from git, http, and rsync
repositories, and optionally stores the retrieved refs in the
local repository under the same name.

To access a git URL, git-peek-remote command is used.  An http
URL needs to have an up-to-date info/refs file for discovery,
which will be introduced by a later update-server-info patch.
