Adjustable array not adjustable

if multidimensional array is created as non-adjustable, it can be adjusted
(new array is created).

if multidimensional array is created as adjustable, it cannot be adjusted:
adjust-array signals "ADJUST-ARRAY: unsupported case." error.

for one dimensional array (vector) all is well.

while i understand that this is probably just feature missing, this appears
to be weird: if you want array to become adjustable, it becomes not.
