From 7b4ed5941c0d2143cb4467a9e265993121b62ce7 Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Thu, 11 Aug 2011 23:19:36 -0600 Subject: t6042: Add a pair of cases where undetected renames cause issues An undetected rename can cause a silent success where a conflict should have been detected, or can cause an erroneous conflict state where the merge should have been resolvable. Add testcases for both.
