\raise in markup (lilypond 1.7.13)

[Alexandre Beneteau]

Hello,

I'm trying to raise text markup with lilypond 1.7.13.
I believe I've followed the manual instructions... but can't achieve 
what I'd would like to.

Please see the source and png output attached...

Thanks,

        Alex.

\include "italiano.ly"

\header { tagline = "" }

\score {
  \notes {
    do''4^\markup { "test" }
    do''4^\markup { \raise #2.0 "test" }
    do''4^\markup { \raise #2.0 { \italic {"test"} }
  }
}}
