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?
