Thanks for the patch.  FWIW, I only noticed that str.replace didn't 
create copies after seeing the results in a benchmark; I was testing 
different ways of doing html quoting, and noticed that str.replace was 
pretty fast when it didn't have to do any work.  So in a small way these 
things can be noticeable.
