      edit [item]
        Edits either the todo.txt, done.txt, or
        todo.cfg files. If no arg is supplied, todo.txt
        will be edited. If a numeric item number is
        supplied, the todo.txt is edited, with the cursor
        sitting on that line (assuming you use vi or emacs). 
        The editor invoked uses the EDITOR environment
        variable, or defaults to vi.
