can `shuffle-vector' be moved?

[Ted Zlatanov]

I don't know where it should live, but cookie1.el doesn't seem like the
right place.

It should be documented in "(elisp) Vector Functions" as well.

Let me know if I should do this, please.

Also this loop call from Pascal Bourguignon is a nice CL alternative to
`shuffle-vector', though it uses the same algorithm:

(defun shuffle (vector)
  "Re-orders randomly the vector."
  (loop
      for i from (1-  (length vector)) downto 1
      do (rotatef (aref vector i) (aref vector (random i)))))

Can it go into cl-macs.el?

Thanks
Ted
