Sparse is clearly wrong.

I went back to my old K&R book, and the "perhaps in braces" languager
is there in that original (ok, so I only have the "newer" ANSI version
of K&R, so I'm not checking the _original_ original).

I guess we might as well ignore the sparse problem, since sparse ends
up having issues with so many other newer things we're doing, and we
don't have anybody maintaining it.
