[vorbis-dev] Argh, preecho mistriggers

This also means that Vorbis is currently wasting bits and hurting sound quality
at the same time...  The *good* news is that fixing the problem will
silmultaneously make things smaller and higher quality.  The sample in question
codes perfectly at 98kbps when I turn off short blocks...
