In general, I agree. Calling directory-files with COUNT being 0,
literally, doesn't make sense. But COUNT could be the result of some
arithmetics, and instead urging the caller to test it, we could simply
return nil. Which is correct, reading nil as the empty list.

And it doesn't cost us anything.
