 \tcode{p<=q} and \tcode{p>=q} both yield \keyword{true} and \tcode{p<q} and
-\tcode{p>q} both yield \keyword{false}. Otherwise, if a pointer \tcode{p}
+\tcode{p>q} both yield \keyword{false}. Otherwise, if a pointer to object \tcode{p}
 compares greater than a pointer \tcode{q}, \tcode{p>=q}, \tcode{p>q},
