From 9c855c31786b9e879ef4cd3b8b5aa97bc4bcf8ec Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Mon, 9 Nov 2009 09:04:42 -0600 Subject: [PATCH] Show usage string for 'git grep -h' Clarification: the following description only talks about "git grep -h" without any other options and arguments. Such a change cannot be breaking backward compatibility. "grep -h" cannot be asking for suppressing filenames, as there is no match pattern specified.
