When we are on a detached HEAD, there is no current branch. There is no reason to leak the error messages to the end user since this is a situation we expect to see. This adds -q option to git-symbolic-ref to exit without issuing an error message if the given name is not a symbolic ref. By the way, with or without this patch, there currently is no good way to tell failure modes between "git symbolic-ref HAED" and "git symbolic-ref HEAD". Both says "is not a symbolic ref". We may want to do something about it. Signed-off-by: Junio C Hamano <junkio@cox.net>
