From 3672c971483020ba5255576aec0be670c76d019b Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Thu, 11 Aug 2011 23:20:22 -0600 Subject: [PATCH] merge-recursive: Fix working copy handling for rename/rename/add/add If either side of a rename/rename(1to2) conflict is itself also involved in a rename/add-dest conflict, then we need to make sure both the rename and the added file appear in the working copy.
