Old documents could change if you did that, and that's a bad thing.

As I told Kirill (and as he rudely deleted when he quoted me), I use 
results=tex frequently, and I had never noticed a problem with this.  In 
my usage (and I'd guess in most people's) I never output multiple 
paragraphs in paragraph mode from a code chunk.  I would normally just 
write that in the LaTeX part of the document.  The results=tex usage is 
for the case where I am constructing complicated LaTeX macros (e.g. for 
tables), that are too tedious to type by hand.

I can imagine cases where I would output text in paragraph mode, and I 
guess Kirill was trying to do that, but they are rare, and it would cost 
less for the users of those rare cases to change the strip.white default 
than it would for everyone else to do it.
