Sorry for leaving your new mail unanswered for so long
(although I marked your mail with the "read-later" tag :)

Finally we have the best solution where the prompt is concise and
fits into one line, still allowing to show more information on demand,
thanks for that.

Some minor details that I still don't understand:

1. Why there is the verbose option “toggle [D]etails”
   while just “[?]” should be enough.  For example, like
   in query-replace typing ‘?’ displays the Help window,
   just typing ‘?’ here could display the Dired Help.

2. Would it be possible to customize the prompt to accept
   short answers “y, n” instead of long answers “Yes, No”?
   When ‘read-answer-short’ is ‘auto’ by default,
   the behaviour of ‘read-answer’ depends on whether
   `yes-or-no-p' is set to `y-or-n-p'.  In this case
   ‘read-answer’ accepts short single-key answers.
