Valentin is already working on giving
define-builtin-markup-command an extra argument for "category",
and when we build the list of markup commands for the docs, we'd
group them by category.  He had a preliminary patch which worked
(but was ugly) that I rejected a week or two ago.

I don't know precisely what Han-Wen and Mats were talking about,
though; it's beyond my understanding of the lilypond internals.
