When setting a control the control's new value is compared to the current value twice: once by new_to_cur(), once by cluster_changed(). Not a big deal when dealing with simple values, but it can be a problem when dealing with compound types or arrays. So fix this: cluster_changed() sets the has_changed flag, which is used by new_to_cur() instead of having to do another compare.
