Would this psuedocode work?

(progn

  ;; Possible values: nil, 'quick, 'verbose

  ;; (defconst yes-or-no-option nil) 

  ;; (defconst yes-or-no-option 'quick) 

  (defconst yes-or-no-option 'verbose) 

  ;; If nil, yes-or-no-p and y-or-n-p will work their traditional ways

  ;; If 'quick , both yes-or-no-p and y-or-n-p will work like y-or-n-p

  ;; If 'verbose , both yes-or-no-p and y-or-n-p will work like yes-or-no-p

  ;; yes-or-no-p now implemented in elisp instead of C

  (defun yes-or-no-p (prompt)

    (if (eq yes-or-no-option 'quick)

        (message "y/n")

      (message "yes/no")))

  ;; y-or-n-p redefined

  (defun y-or-n-p (prompt)

    (let* ((orig--yes-or-no-option yes-or-no-option)

           (yes-or-no-option (if (eq orig--yes-or-no-option 'verbose)

                                 'verbose

                               'quick)))

      (yes-or-no-p prompt)))

  (message "yes-or-no-p:")

  (yes-or-no-p "Q? ")

  (message "y-or-n-p:")

  (y-or-n-p "Q? ")

  nil)

Feeding emacs -batch _from_ a script.  Meaning the script supplies "yes"
and "no".

Same as above.  External input translated into a source for consumption
by Emacs.

"why" is phonetically the same as "y".  Which means that it's likely
harder to generate just "y" from voice than "yes".
