-@c in GNU Emacs 22, additional documentation to kill-new:
-@ignore
-Optional third arguments YANK-HANDLER controls how the STRING is later
-inserted into a buffer; see `insert-for-yank' for details.
-When a yank handler is specified, STRING must be non-empty (the yank
-handler, if non-nil, is stored as a `yank-handler' text property on STRING).
-
-When the yank handler has a non-nil PARAM element, the original STRING
-argument is not used by `insert-for-yank'. However, since Lisp code
-may access and use elements from the kill ring directly, the STRING
-argument should still be a \"useful\" string for such uses."
