From 41d70bd6a94d1bd1ec09d2a3d6ebd419abb25bca Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Mon, 20 Sep 2010 02:28:47 -0600 Subject: [PATCH] merge-recursive: Small code clarification -- variable name and comments process_renames() had a variable named "stage" and derived variables src_other and dst_other whose purpose was not immediately obvious; also, I want to extend the scope of this variable and use it later, so it should have a more descriptive name. Do so, and add a brief comment explaining how it is used and what it relates to.
