RE: bar lines and lyrics

[James Moore]

I use ChoirStaff instead of StaffGroup.  It doesn't draw bar lines down
through the lyrics.

                                % a little smaller so lyrics can be closer
to the staff. 
                 \StaffContext
                 minimumVerticalExtent = #'(-3 . 3)
