I just remembered that I whipped up a script a while back that
does a side-by-side of the differences using Algorithm::Diff.
Right now it does the whole file, but it could be modified to
skip the unchanged bits.  It should probably use CSS, but oh
well.

It's at http://remmler.org/diff.pl if you want to take a look.
