This is a REGRESSION.  With Emacs 23.4, emacs -Q C-h k, same
recipe, you see this:

 <menu-bar> <options> <line-wrapping> <truncate> runs the command
 (lambda nil (interactive) (if visual-line-mode (visual-line-mode 0))
 (setq word-wrap nil) (toggle-truncate-lines 1)), which is an
 interactive Lisp function.

 It is bound to <menu-bar> <options> <line-wrapping> <truncate>.
