I see that someone who has the whole picture in mind can get the effect they want, but it's simpler to have only one case to handle in the first place (is $trace_frame -1?) than two (is $trace_frame even set? what is it set to?). But I think you all understand what I've been trying to say. All the persuading that's going to happen has already happened. :)
