according to my tests, it works perfectly. I also tried your version in 
a couple of scores where I previously had issues with the original 
version (probably the same problem, but I don't remember exactly) and 
thus commented it out, and couldn't spot any flaws.

Thanks a ton!


That is, unless I additionally engage
  http://lsr.di.unimi.it/LSR/Item?id=1090
to replace Lily's built-in hyphens by the "proper" Lyric's font hyphens; 
then it breaks again.

I did not have a very close look yet; I thought replacing ly:stencil? by 
(not ly:stencil-empty?) might help, but that's not it. I'll give it 
another shot as soon as time permits.
