That's sort of the question. Is it OK if a graphic or superscript in a
programlisting causes all of the line numbers to be weirdly
out-of-sync?
AFIACT, all of the table solutions I've seen online apply specifically
to plain-text program listings, where there's no opportunity for other
things to appear.
In DocBook, other things can appear. Is that the author's problem,
the production editor's problem, or the stylesheet's problem?

I think we can make the callout case work. We can use CSS to adjust
the line-height so that callouts don't cause a problem. The more
pressing issues are: what about cases where CSS isn't applied and what
about program listings that contain other line-height-altering markup?

Because that won't help. There could still be a superscript or image
(think inlinemediaobject) in the programlisting.

It's hard alright.
