Obvious workaround is to make our function check that the context it's called with matches our jianpu voice, but I'm not sure how to do this other than by setting a property that's not otherwise used, which we can test for in the function. So I'm 'commandeering' the "chordChanges" property (there since at least 2.15 and used by Lilypond only when it's in chord mode, which we don't use, and if someone adds a chord-mode staff then it won't print noteheads anyway): we will substitute jianpu numbers for noteheads only if chordChanges = #t.
