Well, it's not my code, it's Gregory's. I just evaluated it and it
seems to be working decently for the day or so. But I'm fine to admit
there may be corner cases where it would fail, I just haven't detected
those failures.

Don't worry. I meant I have that variable set to 3, but I'm seeing a
6-line-high minibuffer prompt, so something in Gregory's code seems to
be overriding it. By "should be" I'm stating that that overriding
shouldn't happen, i.e. I'm searching for a better solution.

Truncation is being given something to display, such as here:
(let ((minibuffer-setup-hook (lambda ()
(insert (format "one\ntwo\nthree\nfour")))))
(read-minibuffer "hey"))
and _not_ actually displaying it becasue of some window size constraint.

Right. But is there a very large cost in implementing a mechanism of
notification that applications can optionally subscribe to take action
when this common thing happens to them?

Thanks, but I don't understand how that could help here. The docstring
says:
This function exists to allow Lisp programs to adjust the dimensions
of WINDOW to the buffer text it needs to display.
But we need a subtly different use which would be:
This function exists to allow Lisp programs to adjust the buffer text
so that it fits visually in WINDOW.
I don't know how to use the function to do this. In other words, I have
some buffer text and I would like to know:
1) If it fits in WINDOW;
2) If it doesn't, where is the cutoff, as a text position.
I'm re-reading the docstring to see it this is possible, but I don't
think the function is tailored for this use case. Anyway, if that
function existed it would be what I called the canonical solution for
this case.
