From 36f5b1f0c800a23b9755a0214c1c3250f34f2486 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Tue, 23 May 2006 19:23:41 -0700 Subject: [PATCH] git-svn: ignore expansion of svn:keywords Unlike my earlier test patch, this also checks svn:eol-style and makes sure it's applied to working copy updates. This is definitely more correct than my original attempt at killing keyword expansions, but I still haven't tested it enough to know. Feedback would be much appreciated. Also changed assert_svn_wc_clean() to only work on the svn working copy. This requires a separate call to assert_tree() to check wc integrity against git in preparation for another change I'm planning.
