From 58a0393154cfced92830fed1a78450761f30f3b9 Mon Sep 17 00:00:00 2001
From: Jonathan Gordon <rockbox@jdgordon.info>
Date: Mon, 19 Apr 2010 08:43:42 +0000
Subject: 2 quick fixes 1) fix %pv| where the | is for a conditional break and
 not for long form %pv 2) only draw bmp-bars if they are enabled (by a
 conditional or always on.)
