From: Jonathan Nieder Date: Mon, 09 Nov 2009 15:04:48 GMT Subject: [PATCH 08/24] Show usage string for 'git check-ref-format -h' Message-ID: <1257779104-23884-8-git-send-email-jrnieder@gmail.com> In-Reply-To: <20091109150235.GA23871@progeny.tock> 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.
