docstring: Toggle overwrite mode. With an explicit positive numeric
          argument, switches to overwrite mode. With an explicit non-positive
          numeric argument, switches to insert mode. This command affects only
          emacs mode; vi mode does overwrite differently. Each call to
          readline() starts in insert mode. In overwrite mode, characters
          bound to self-insert replace the text at point rather than pushing
          the text to the right. Characters bound to backward-delete-char
          replace the character before point with a space.
