[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).
