Comment #2 on issue 2946 by [email protected]: stroke fingers and string numbers suppressed when combined with lyrics
http://code.google.com/p/lilypond/issues/detail?id=2946
Ok, here is what likely goes wrong: for articulations on non-chords, the rhythmic_event_iterator looks whether anybody is listening to them in which case it siphons them off the rhythmic event and broadcasts them in the expectation that somebody will look out for them. Otherwise it leaves them on where the New_fingering_engraver (?) might pick them up.
It would now appear that the Lyric_combine_music_iterator listens to everything without actually looking at it much, triggering this mechanism. So we would need to make it listen more selectively.
