[racket] Line folding in DrRacket

Thanks Danny, but this actually transforms the text into non-pure text
files.
I'd like the same thing (collapsing s-exp is even better than lines), but
without modifying the file, i.e., the folding is just a /view/ of the file
(and because of this, I think line folding is easier than s-exp folding).
