If we have a situation where reduce bits should be taken from the M
channel instead of the S channel, then LAME is supposed to detect that
and encode the frame in regular stereo, not M/S.  

If you want to pursue this idea, you might want to try forcing
all frames to be M/S using the "-m f" option.
