Reproducing lawlist's comments here, To make an overlay and minify the code block as "...", you can do,
(overlay-put (make-overlay (point-at-bol) (point-at-eol)) 'display "...")
Now, to expand the contents and bring the buffer to its original form,
(remove-overlays (point-min) (point-max) 'display "...")

I'm not picky -- anyone can write-up an answer, even yourself if you are so inclined. – lawlist Feb 27 '15 at 17:38
