[Vorbis-dev] Patch to stop vcut from generating broken streams

[Michael Vrable]

I also realized not long after sending the patch that this patched line
in process_second_stream:
ogg_int64_t packetnum=1; /* First packet is header, already written. */
should really read:
ogg_int64_t packetnum=3; /* Header packets have already been written. */

(Though I actually don't think this value affects the output bitstream
at all.)
