[vorbis-dev] batch encode broken oggenc rc3

...even worse, it *appears* to work, and produces crap files.

When specifying a -b <foo> option for a batch encode, -b <foo> is only
obeyed for the first file.  All subsequent files encode with the
equivalent of -b 0 (despite the chatty text output claiming otherwise)
resulting in overly low bitrates that sound like shit.

I don't know if this affects -q as well, but it a safe enough bet to check.

This bug has also been logged in bugzilla by the user (I stepped him
through it).  This needs to be fixed ASAP.

Output from the user (JonoF) who originally reported it... note that
the second encoding of main.wav is clearly borked:
