Fl_Input_Choice::menubutton() returns a pointer to the underlying
Fl_Menu_Button inside the widget, letting you access all the usual
menu methods, including size() which returns the size of the menu.
In short:
int howmany = choice->menubutton()->size();
Note the size() count includes the terminator at the end,
so if you add() 3 items, the size() will be 4.
For more info, see Fl_Menu_::size(), eg:
