The good news is that I have the independent scroll behavior that
I wanted. There are two bits of bad news. The first is that I don't
UNDERSTAND why this particular configuration, with an extra level of
nesting, made any difference.
The bigger problem is that I still don't see the scroll bars showing
up at all. And that annoys me. I should see them, right?
Improved the look of Definition Lists, but I think we're gonna
need a couple of flags on the macro to supply different base
classes, because I don't think I really like using the CODE style
with its yellow background, at least not the one in the default
template, and because I think we're gonna need a distinction between
a "tight" list (where the dt & dd share a line) and a standard
list (where they don't.)
