Of course, people write a loop like this

	char *cp, *ep = strchr(string, '\n');

	for (cp = string; cp < ep; cp++)
		...

all the time, and forbidding pointer comparison would make the
language impossible to use ;-)

I think you are confused with a different rule---what is not kosher
is to compare two pointers that do not point into elements of the
same array.  Whether the comparison is done in (ptr1 < ptr2) way, or
(ptr2 - ptr1 < 0) way, does not change the equation.
