> What about -global_quality and -q:a?

Well the way it is handled is bit messy. The q:a is converted to
lambda units through QP2LAMBDA, and then interpreted as a vbr value.

So the -q:a value does not correspond to a VBR mode as probably
expected. I'm keeping documentation for global_quality, as in the
first patch.

[...]

I'll push the patch soon if I see no more comments.
