Well, more than that, neither the second or third header is currently
guaranteed to occupy only a single page (together or each). I'll
probably limit both, temporarily for Vorbis I, to one page max, but it
won't stay that way in the long run.
Write the code to always run. Convenience isn't always a virtue.
