This is the correct behaviour, but I don't think it's necessarily the
case, any more than people put (say) XviD in OGM instead of XviD in AVI
in OGM. I believe that what is considerably more likely to happen, given
the tendency towards the latter, is that people encode a Vorbis file
separately (which then ends up in its own Ogg container) and then mux
*that* file, container and all, into an OGM.

It's possible (haven't looked) that this doesn't actually happen, but if
so I'd be very surprised, since there are AFAIK no Vorbis encoders which
do not also automatically mux the resulting audio into an Ogg and hence
no way to get "clean" Vorbis for muxing into another file.

(I'm surprised I'm posting this, after feeling like such an idiot less
than a hour ago over my idiotic post to the CVS-log list... perhaps I'm
just a glutton for punishment.)
