Basically, this works as google books does. Along with the diff link, a user is able to add in text to the url in lieu of how one would for a google books link(or something similar) in order to highlight specific text in the diff to point out something specific if the diff is really large. This could have any number of applications.
What Daedalus wants, if you don't quiet understand him, is that he wants a search option in the diff option that can highlight words in the diff compares.
