Ah, I didn't think of that, but yeah, that would explain Junio's
position a bit more.

Right. They're two separate types of "unused", and they should actually
complement each other (e.g., if we drop an unused strbuf parameter, then
a calling function may find that it is now doing nothing but
init/release on the strbuf). So we'd want both.
