Great to hear that there is a way to get this done, but while my 
scheme-fu is getting
better nearly every day ;-), my understanding of c++ internals is just 
emerging from zero.

Can you give me the needed code changes in 
Pointer_group_interface::find_grob?

Would the overload mechanism work in lily/note-spacing.cc *and*
lily/paper-column.cc? The latter file shows

align
      = Pointer_group_interface::find_grob (me, ly_symbol2scm ("elements"),
                                            (align_sym == ly_symbol2scm 
("staff-bar")
                                             ? Bar_line::non_empty_barline
                                             : 
Break_alignment_interface::has_interface));

Thanks for your help!

Regards,

Marc
