I suppose I could have just put an early return for NV12/21 and
leave the rest as is. But it's a fairly tiny diff so figured it's
still legible even after diff mangles things in its usual silly way.
But I can redo it in whatever way people prefer.

I wonder if anyone's ever implement a diff algorithm that actually
makes good patches? At some point I was thinking that something
which tries to handle C blocks rather than lines might be a
decent approach.

Yeah. It explodes in some interesting ways if the Xv adaptor supports
the specified format but vo_xv doesn't. I thought about fixing it, but
then I decided that if it's been like this all these years no one
likely cares ;)
