Up to 30 characters, but there has to be whitespace after it (to keep  
it from splitting in the middle of the word) or be the very end of  
the string. The greedy regexp will grab all 30 if it can find them  
with whitespace after, otherwise it will backtrack until it finds the  
right spot.

Very nice, Erik. I like how it also strips the whitespace that will  
be wrapped.
