The In-Between barlines are not a special thing. You need to use a StaffGroup, 
which has barlines in between by default. The snippet just shows how to not 
engrave the barlines which are in the staff itself. So whats left is the part 
of the barline in between.
Don't forget to enable engraving again at the end of the piece (or you will not 
have a final barline. The starting barline is there by default)
