Yes, although the only place that I can find which clearly says
so is footnote 79. Apart from that, pointer arithmetic appears
to be defined in a rather circular manner, although you can sort
of infer the contents of footnote 79 from footnote 82 (I can't
find anywhere else that says array elements are adjacent).
