As I said - the code isn't really full of errors, mostly style differences. I am now the maintainer of the code, and for purpose of maintaining it - Id prefer it to be readable - to me, I am more concerned about stepping on toes and how some people here might deal with that. I have great respect for the people who wrote the code.

Thanks for your suggestion of writing tests - my background is not in softare development, and its been suggested enough times to me by people who know and seems like a logicaland reasonable thing to do...

thanks
