From 8951d7c1f1ae38f34617b6c2490bf65e73e371f7 Mon Sep 17 00:00:00 2001
From: Daniel Barkalow <barkalow@iabervon.org>

Subject: Build in ls-remote

This actually replaces peek-remote with ls-remote, since peek-remote
now handles everything. peek-remote remains an a second name for
ls-remote, although its help message now gives the "ls-remote" name.
