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. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
