RE: `y-or-n-p' does not wait for input - assumes `n'

[Drew Adams]

       I'm probably missing something, but shouldn't y-or-n-p insist on a
       character `y' or `n' input event?
    
    Yes, but you can enter any event you like as response to y-or-n-p.  It
    will be read.  If it is not y, Y, n, N, <SPC>, <DEL>, C-] or C-g,
    y-or-n-p will respond by asking the more emphatic form of the question.

       How could a mouse event be used to answer the question?
    
    Richard's quote said: "tried to answer the question".
    
Got it. Thanks.
