Also, in the case of SpinButton::signal_input(), it should return a bool, but it currently returns a plain int. I guess it was hastily wrapped, way back when.

Ah. It is documented as being able to return a Gtk::INPUT_ERROR, so that's why it's an int. Perhaps a real enumeration would be cleaner in this case? With enumerators like {unhandled, success, input_error}.
