## return-nil-from-pop-up-dialog

Arguments: widget new-value old-value

The default on-click function for a `cancel-button`.

This function simply calls flag-modal-completion with a value argument of `nil`, if the widget's parent dialog is currently being invoked in the current process by a call to pop-up-modal-dialog. Otherwise it does nothing.
