From c591412cc0aaf10890cdda4cf97a4fbc782d7d49 Mon Sep 17 00:00:00 2001 From: Dan Holmsand Date: Mon, 20 Jun 2005 20:52:38 +0200 Subject: [PATCH] git-resolve-script: Add LAST_MERGE and use git-rev-parse Make git-resolve-script only write MERGE_HEAD if a merge actually occurred. All merge failures leave ORIG_HEAD and LAST_MERGE behind (instead of ORIG_HEAD and MERGE_HEAD). Use git-rev-parse to expand arguments (and check for bad ones).
