and another request

if we have 'fragmented' enum like

                     scene_mode 0x009a091a (menu)   : min=0 max=13 default=0 value=11
                                0: None
                                8: Night
                                11: Sports

code is unable to enum this menu fully and cannot allow to change value

proposed patch: seems works as expected without side effects
