The condition change seems unnecessary, given that the new one does the 
exact same logic.

I'm in favor of changing the bf default, even though it technically 
changes behavior of existing command lines.
It seems counter intuitive that the encoder would gimp itself by 
disabling bframes by default.

If no one objects, I will apply this.
