From 3bc427e01342a5a6ae2052d27373f8759c680398 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Thu, 12 Mar 2009 00:00:56 +0100 Subject: Documentation: filter-branch: show --ignore-unmatch in main index-filter example Rearrange the example usage of git filter-branch --index-filter 'git rm --cached ...' so that --ignore-unmatch is in the main example block. People keep stumbling over the (lack of this) option to the point where it is a FAQ, so we would want to expose the most common usage where it stands out.
