There is no reason to use git-sh-setup from git-ls-remote. git-parse-remote can help the caller to use .git/remotes shortcut if it is run inside a git repository, but can still be useful outside a git repositoryas long as the caller does not use any shortcut. Use "git-rev-parse --git-dir" to figure out where the GIT_DIR is, instead of using git-sh-setup. This also makes "git-ls-remote origin" to work from inside a subdirectory of a git managed repository as a side effect. Signed-off-by: Junio C Hamano <junkio@cox.net>
