It's used in the next patch in the cbmem utility. But more importantly, it's just here for documentation purposes. I tried a bunch of different ways to describe in the comment how to use this ("you have to first print this piece and then the string and then this other piece...") until I eventually realized that just giving the printf pattern is really the most clear and unambiguous way to document it.
