Simultaneous rehearsal marks and staff spacing

[Nick Payne]

If I use the first method shown in the LSR for putting two simultaneous rehearsal marks above and below the staff ( http://lsr.dsi.unimi.it/LSR/Item?id=735), but it has the ugly side effect of increasing the spacing above that stave compared to the normal spacing. Is there any way to use this method without affecting the staff spacing?

\version "2.15.43"

\paper {
    #(set-paper-size "a5")
}

\relative c'{
    \repeat unfold 60 { c4 }
    \once\override Score.RehearsalMark #'extra-offset = #'(0 . -9)
    \once\override Score.RehearsalMark #'baseline-skip = #11
    \once\override Score.RehearsalMark #'self-alignment-X = #RIGHT
    \mark\markup\normalsize\right-column { \musicglyph #"scripts.segno" "Menuetto D.C." }

}
