Okay, well, I couldn't find it by evaluating (re-search-forward "^M")

So, given the character can't be inspected, the old code couldn't even
 do anything :)

I suggest to read the node "Selective Display" in the ELisp manual
about this feature, and how the ^M characters come into play.

Ok, the docs say that every newline in "invisible part" is replaced with ^M.

But this doesn't change the fact this ^M can't be inspected, in particular by (looking-at "\^m") that the 2-nd patch removes. I just tested that.

Oh well, whatever, I'm not really motivated to discuss that, let's just drop 2-nd patch. Are patches 1 and 3 okay?
