tdf#134692: copy deep when there are multiple references to the old array
E.g., when we redim a copy of an array, the other copy would still have
its old dimensions, so shallow copy would share some array elements
between the now different arrays.
The other possible approach would be to try to modify the original array
to have the ByRef semantics.
