Oh, well.  I've removed the use of the callback function, and this
does (still) seem to work, so here's a cleaner file.

You're free to (clean it up further as you like and) include it with
LilyPond if you like, of course.

I've also included a .ly file to \include if you want to use this,
mostly as an example.  I guess you want a regression test, too?
