Re: yes-or-no-p prompt conditionally broken in master?

Of course I forgot to mention that (message "y/n") is supposed to be the traditional y-or-n-p implementation and (message "yes/no") is supposed to be the traditional yes-or-no-p implementation.

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".
