Per request, I have attached a context diff for both bz2.txt and 3.0.txt suitable for http://docs.python.org/library/bz2.html and http://docs.python.org/release/3.0.1/whatsnew/3.0.html respectively. 

The modification in bz2.txt may border on redundant and overly verbose and should be reviewed for style consistency.

I have sanity-checked the modified files with sphinx-build html which generates clean, consistent markup.
