From 9bc0619655dfd183eb5d0d47b4d63a511acd5c64 Mon Sep 17 00:00:00 2001 From: Kirill Smelkov Date: Mon, 24 Feb 2014 20:21:41 +0400 Subject: [PATCH] tree-diff: rename compare_tree_entry -> tree_entry_pathcmp Since previous commit, this function does not compare entry hashes, and mode are compared fully outside of it. So what it does is compare entry names and DIR bit in modes. Reflect this in its name. Add documentation stating the semantics, and move the note about files/dirs comparison to it.
