My knowledge of Guile is too limited to agree or disagree, but my gut
feeling is that such clean-up work is a good starting point for people
who want to get more intimate with LilyPond.  Using Guile as
envisioned by its creators is not a bad thing, is it?  To exaggerate,
it is possible that you, Han-Wen, as a Guile developer, know too much
about its implementation details.  Anybody else is bound to the
documentation, and as long as you don't say that the Guile docs are
incorrect w.r.t. David's issue, I favor a conversion to the `correct'

BTW, I've started in a similar way while developing FreeType, and
today I'm the main maintainer :-)
