Before this gets out of control, I recommend two new
options :

 --bitrate  <desired bitrate>
 --mode   <desired mode>

and deprecate the -b option as an experimental/backward
compatibility/mistake/whatever thing. ( also make it print
a big warning, informing the user about the state of things )

Most users would then use --bitrate and get what they expect.
Others ( developers ) can then still select a mode directly
with --mode, if they want to.

The names of this two options could something different off course
( --codebook ? ) and one letter version should also be available.
