[&1.6] This is related to issue 3406 and r7772. It solves the failing BON tests on 1.7, but its rather more change than needed.  In particular I believe the BON fix is only the return value from highlightExecutionLine. But the rest cleans up show(), which as a lot of cases, few of which are tested. The current form should be easier to test and read, but I think it forces users to reload in cases where they may not have needed to before, eg opening firebug part way through a page load.
