Well, at least as much as the resulting sizes tell you, if not more.
The subtle difference: your approach is _expensive_ in terms of CPU time,
while the byte change approach is _dirt cheap_.
I don't dispute that for a second.
Since it seems that there are gazillions of examples where one or the
other (or both) do not make sense, I'd rather have the fast one.
Fair enough.
