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. Signed-off-by: Kirill Smelkov <kirr@mns.spb.ru> Signed-off-by: Junio C Hamano <gitster@pobox.com>
