From cbb3167ef8b73109ed5c5e54aa1915d9c50f83d5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Fri, 22 Oct 2010 01:48:14 -0500 Subject: [PATCH] ls-files -h: show usage even with corrupt index MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Part of a campaign to avoid git -h being distracted by access to the repository. A caller hoping to use "git ls-files" with an alternate index as part of a repair operation may well use "git ls-files -h" to show usage while planning it out.
