bug#13841: 24.3.50; Regression - unreadable `C-h k' help

["Drew Adams" <drew.adams@oracle.com>]

emacs -Q
 
C-h k
 
Then choose menu item Options > Line Wrapping in This Buffer > Truncate
Long Lines.
 
You see binary output instead of useful help:
 
<menu-bar> <options> <line-wrapping> <truncate> runs the command #[nil
"ILLEGIBLE, INCOMPREHENSIBLE BINARY INCANTATIONS" [visual-line-mode
word-wrap 0 nil toggle-truncate-lines 1] 2 nil nil], which is an
interactive compiled Lisp function.
 
It is bound to <menu-bar> <options> <line-wrapping> <truncate>.

Not documented.
 

For reference wrt this regression, this is what Emacs 23.4 shows
instead - much more readable and helpful:
 
<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>.
