Fix "wrong varnullingrels" for Memoize's lateral references, too.

The issue fixed in commit bfd332b3f can also bite Memoize plans,
because of the separate copies of lateral reference Vars made
by paraminfo_get_equal_hashops.  Apply the same hacky fix there.

(In passing, clean up shaky grammar in the existing comments
for this function.)
