SVN Book diff idea for the HTML version

It would be nice to have SVN book versions on the website that have a
differing portions of the text in blue for changes, and green for new
additions and red for now obsolete parts.

It would make re-reading the book for a new version much easier for old
hands, you could immediately spot everything you need to reconsider.

So, if I upgrade from 1.6 to 1.7, I would like to have the normal 1.7 book,
the 1.7/1.6 'blue/green' version and the 1.6/1.7 'red' version.

(blue & green might not be possible to automate, but even just the blue
version would be very useful, or perhaps it's even possible to have this
all in one version.)

regards,

Gabriela
