From 838338cd22c1df53c1460d9239780371a234b242 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 29 Aug 2008 08:16:30 -0700 Subject: [PATCH] xmerge.c: minimum readability fixups This replaces hardcoded magic constants with symbolic ones for readability, and swaps one if/else blocks to better match the order in which 0/1/2 variables are handled to nearby codepath.
