There's some misunderstanding here: what I had in mind was to insert
the minibuffer contents into the echo-area buffer, put the point after
that, and then insert the text which 'message' was called to display.
With this, window-start will be at point-min of the echo-area buffer,
or am I missing something?

IOW, I don't understand why you are worried about window-start, since
it should always be at point-min, and the mini-window should resize to
show all the text.
