d'oh; I must have been tired as well. Obvious workaround: revert 
LyricWord.after-line-breaking (or override to ##f) at the problematic

Thank you, that's what I should have done immediately when posting; 
sorry about that.

You forgot to attach the PDF, but I have an idea about what you did and 
observed, and what significant difference you point to; I'll try to 
investigate further as soon as possible.


Thanks again,
