Actually, `C-h' is useful in `y-or-n-p' as well for the same reasons.
For example, `C-h b' in a `y-or-n-p' prompt shows:

  Key             Binding
  y               act
  n               skip
  C-l             recenter
  ...

BTW, (info "(emacs) Yes or No Prompts") says:

     With both types of yes-or-no query the minibuffer behaves as
  described in the previous sections; you can recenter the selected window
  with ‘C-l’, scroll that window (‘C-v’ or ‘PageDown’ scrolls forward,
  ‘M-v’ or ‘PageUp’ scrolls backward)

But in fact ‘C-l’ doesn't scroll the window, ‘C-v’ and ‘PageDown’ don't
scroll forward, and ‘M-v’ and ‘PageUp’ don't scroll backward.  Should they?
