`yank' and `yank-pop' use `current-kill' to rotate the yanking pointer
in the kill ring.

But maybe `yank-browse' should have its own yanking pointer?

For instance, with the kill ring having the value:

  '("string1" "foo" "string2" "bar" "string3")

this scenario would be useful:

M-y str RET    ;; the user types a substring "str" in the minibuffer
               ;; and RET inserts "string1" to the current buffer
M-y            ;; reinserts "string2" to the current buffer
M-y            ;; reinserts "string3" to the current buffer
M-y            ;; reinserts "string1" to the current buffer
