! This routine can be used in two modes:
! 1. Normal: just look at the col indices and trust them. This
! implies putting in empty cols where needed. In this case you
! can get in trouble if A%M < A%IA1(NZA)
! 2. Shrink mode: disregard the actual value of the col indices,
! just treat them as ident markers. In this case you can get in
! trouble when the number of distinct col indices is greater
! than A%M
