What don't you understand about it?  (To quote a famous person.)

I don't think so.  `resize-mini-windows' will do nothing for a
standalone minibuffer.  Again: "Don't show a multi-line message
for prompting `y-or-n-p' in the echo area and expect users to see it."

It is NOT a good idea to depend on `resize-mini-windows' showing
all of a multi-line message.

If the code _really_ needs to interact with the user using a
multi-line message, then `y-or-n-p' is the _wrong_ way to ask
the question.  If users need to read multiple lines then hitting
a single key to choose is probably not appropriate.

This should be rethought, IMO.  If the prompt cannot reasonably
be a single line then some other interaction should be used.
Do not just look for a way to force minibuffer-window resizing.
