Depends. the header bursts on bumpers are already an issue. Also, some
games encode short sound effects where the padding would be a notable
waste.

This is correct behaviour, btw. In the Ogg Theora files, the comments
on the first (theora) stream are by default assumed to cover the whole
group. Patching libvorbis doesn't help with that.

Only the encoding application knows this, of course. Another argument
for size request in the API, and deciding separately what oggenc's
policy should be.
