I had this problem earlier and solved it here:

http://groups.google.com/group/comp.lang.python/browse_frm/thread/6df6e6b541a15bc2/09f28e26af0699b1

thanks to a little guidance from Ben Finney on where to look.

It came up again last month here:

which should solve the problem for you.

ASIDE:  I've started refactoring this bit out in my local 
source...how would I go about contributing it back to the Python 
code-base?  I didn't get any feedback from posting to the Optik 
site.  My refactor basically takes an optional pre-processing 
function to parse your string into the output that gets passed to 
textwrap.wrap() and textwrap.fill(), defaulting to the old 
behavior, but offering a function for splitting it into 
paragraphs based on newlines.
