Modes:
 
(define-minor-mode hungry-mode
       "Toggle Hungry mode.
     With no argument, this command toggles the mode.
     Non-null prefix argument turns on the mode.
     Null prefix argument turns off the mode.
 
     When Hungry mode is enabled, the control delete key
     gobbles all preceding whitespace except the last.
     See the command \\[hungry-electric-delete]."
      ;; The initial value.
      nil
      ;; The indicator for the mode line.
      " Hungry"
