[PATCH] git-peek-remote: show tags and heads from a remote repository.
Add a git-peek-remote command that talks with upload-pack the same way git-fetch-pack and git-clone-pack do, to show the references the remote side has on the standard output. A later patch introduces git-ls-remote that implements a UI to store tag values retrieved using this command.
