What are these changes for, except perhaps to make the patch larger than
necesssary to make it harder to review?
It would leave an unnecessary SP like 'class="diff "' when all the arms of
if/elsif cascade fall off and $diff_class is left empty. It isn't a major
issue (I suspect that such a case might even be an error), and I even
think the code after the above patch would be easier to read and more
sensible, but shouldn't that kind of "style fix" be in a separate clean-up
patch that does not introduce any new feature?

And everything else, including this hunk to change what is returned from
the subroutine belongs to a separate patch that implements the side-by-side
feature.
