Hi Alexander

Yes.

Currently we get a short extender ... that is imho of no use and should be 
killed.

No really ... but ... yes. In a situation like << { c1 } { a8 (g f g a2 ) } >>  
it could be usefull.
Would need an override ...

The 2nd part of the extender is killed by the "if (heads.size () < 2)". That could be changed to "if 
(left_edge->internal_has_interface (ly_symbol2scm ("lyric-syllable-interface")) && heads.size () < 
2)".

It's late now, good night.
