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.
