  parameters and will copy them across to the new parameters if the
  new parameter does not yet have a saved value. It then saves the new
  value.

  Note that this works even if the old parameter has been removed. It
  relies on the old k_param index not being removed

  The second column below is the index in the var_info[] table for the
  old object. This should be zero for top level parameters.
