[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.
