Since there was some interest in my old script for diffing webpages I published them in my blog. Then an extension to watch git repositories was added. As there is more ongoing interest, I decided it is time to provide a cleaner way of obtaining this script then looking at a blog and collecting patches from follow-up blog entries. wwwdiff is now available via anonymous git, just
git clone git://git.linta.de/aehlig/wwwdiffand use under a 2-clause BSD-style licence. Feel free to use said script to watch this repository for updates.
