Ragged right on last 2 bars.

[Peter Terpstra]

Dear People,
Is it possible to apply the ragged-right paper option in such a way that only 
the last 2 bars will be effected?

Thanks in advantage!

Example:
\version "2.18.2"
\paper {
  indent = 0
  ragged-last-bottom = ##t
  ragged-right = ##t
}
\score {
  \relative c' {
   \repeat unfold 12 {a'4 b c d}\break
   <e, b' d gis> r <a, c' e a>2
   \bar "|."
  }
}

Peter
