Avoid overlong lines in example

I am not happy with this.
Because it is too long vertically now.

But before it was overflowing the box used to display it in the docs,
so was unreadable.

I think maybe the real solution is to remove some of the common subexpressions to be elsewhere defined and reused

Yeah, that's probably what should happen.
