From 92d6cd6db896b75ae35ab3412988692c74add88e Mon Sep 17 00:00:00 2001
From: Christophe Jaillet <jailletc36@apache.org>
Date: Mon, 9 Feb 2015 20:32:18 +0000
Subject: [PATCH] Fix a precedence issue. The logic is unchanged but 'ret' does
 not have the expected value. So the logged error message may be incorrect.

+ add some empty lines between functions
