I needed to change the formatter so I could add blockquotes. I 
eventually go it working, but there were a couple of things about it I 
didn't like. My source code is at 
http://aamcf.co.uk/kwikimods/Formatter.2004-11-11.txt, and I'd 
appreciate any feedback - my hacking was strictly at the cargo-cult level.

Doing something similar for 0.18 is covered on
