Again I agree with you.  Hence the request to have a way for the 
application to tell to Emacs: "please display the entire prompt (unless 
it's impossible to do so)".  The code I sent to Andrii does does exactly 
that.

Alas, it is practically impossible to create a text that you can be sure 
will fit / be displayed entirely in the minibuffer window.
