(define-minor-mode show-point-mode
  "Toggle show-point mode.
With no argument, this command toggles the mode.
A non-null prefix argument turns the mode on.
A null prefix argument turns it off.

When enabled, the value of `point' is displayed in the
mode-line (after the line and column numbers, if those are being
displayed too).")
