Add or subtract on pq grid using matching dimel and scalar-dimension

Addition and subtraction on pq grid makes a result with consistent
scalar-dimension and dimel slots, thanks to a second return value from
dimel-or-not and therefore equal-dimension.  Also, a more refined
check on make-pq-object if #+debug holds, so that trying to make a pq
with a scalar dimel and scalar-dimension nil will give an (incorrectly
labeled) error.
