I was thinking (y-or-n-p "foo  ")    => prompt is "foo  (y or n)"

which we could consider fixing (but itʼs long-standing behaviour)

    Stefan>     (yes-or-no-p "foo ") => prompt is "foo (yes or no) "

ENOPATCH 😜

(and as someone pointed out elsewhere `y-or-n-p' and `yes-or-no-p'
could do with some refactoring.
