Minor confusion in array new language

[Mark Mitchell <mark@xxxxxxxxxxxxxxxx>]

	When operator new is used to create a new dynamic-length
	array, a cookie is usually stored to remember the allocated
	length (number of array elements) so that it can be
	deallocated correctly.

It doesn't matter whether or not the number of array elements is known
at compile-time; the choice of whether or not you need a cookie is
independent of this fact.  So, that should just be "used to create a
new array".

Thanks,
