barline at end of staff

[Arno Rog]

L.S.

I'm trying to figure out a way to place the last bar line exactly at the end of 
the staff in the score of the Dutch anthem at 
http://lsr.dsi.unimi.it/LSR/Snippet?
id=648

Now it's done manually: \override Staff.BarLine #'extra-offset = #'(23 . 0)
\bar "|."
Can this be automatically (and correctly)?
