About `current-kill'

[Xue Fuqiao]

In the definition of the function `current-kill':

[...]
      (let ((ARGth-kill-element
             (nthcdr (mod (- n (length kill-ring-yank-pointer))
                          (length kill-ring))
                     kill-ring)))
[...]

I understand what `ARGth-kill-element' does (from its name).  But how
does it work?  I cannot understand it.
