bug#4190: 23.1.50; <prior> and <next> of pc-select.el don't beep

All I know is this doesn't beep/flash when it hits the beginning of the buffer:
  <prior> runs the command scroll-down-nomark, which is an interactive
  compiled Lisp function in `pc-select.el'.

Same for <next>.

However C-p and C-n still beep properly.

You may ask "why am I using pc-select.el". I don't know. It must be due
to http://jidanni.org/comp/configuration/.emacs
