"b" is for bitrate regardless of media type. The specifier that comes 
after it decides the type. You're probably breaking that by making "b" 
no longer be a valid option.

IMO, change the description to "Stream bitrate".

And this just removes "ab" altogether, which is a break with no previous 
warning. b:a already works thanks to "b" above.

Just flag this option as deprecated.
