From aeda85a81547b05c36939defb420e5f02bf05e51 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Mon, 9 Nov 2009 09:04:48 -0600 Subject: [PATCH] Show usage string for 'git check-ref-format -h' This only changes the behavior of "git check-ref-format -h" without any other options and arguments. This change cannot be breaking backward compatibility, since any valid refname must contain a /. Most existing scripts use arguments such as "heads/$foo". If some script checks the refname "-h" alone, git check-ref-format will still exit with nonzero status, and the only detrimental side-effect will be a usage string sent to stderr.
