Arguments: widget
Returns the up-down-control control associated
with the control specific by the argument widget,
if there is one. Returns nil if there is no
associated up-down control. Up-down controls are usually associated
with editable-text controls but the
argument can be any type of control.
If an up-down control (rather than nil) is
returned, applying buddy-widget to that
up-down control should return widget.
