If you know how to do that at all, let alone in a maintainable way (ie
one where inserting a new function doesn't require touching the entries
for the ones after), let's see it.  I agree it'd be a nice solution,
if we could make it work, but I don't see how.  I'd been imagining
instead that we could give a different background color to the first
line of each group; which I don't know how to do but it at least seems
plausible that a style could be attached to a <spanspec>.

Interesting idea.  I'm afraid that it would not look so great in cases
where the example-plus-result overflows one line, which would inevitably
happen in PDF format.  Still, maybe that would be rare enough to not be
a huge problem.  In most places it'd be a win to not have to separately
allocate example and result space.
