Re: dashed span bar for ossia

[Nick Payne]

 In guitar scores I use Postscript to put a dotted line between the 
main and ossia stave. The value for rlineto will need changing if the 
distance between the staves changes:

\version "2.13.35"

#(define ossialine "0.07 setlinewidth [0.85 0.25] 0 setdash 0 -3 moveto 
0 -5 rlineto stroke")

\new Staff = main \relative c' {
    \key a \major
    \clef "treble_8"
    gis16 b e b' e e, b' e gis,, b e b' e e, b' e\mark\markup { 
\postscript #ossialine }
<<
    {
        gis,,, a' cis e a cis, e a gis,, a' cis e a cis, e a |
    }
        \new Staff \with {
            alignAboveContext = #"main"
            fontSize = #-4
            \override StaffSymbol #'staff-space = #(magstep -4)
            \override StaffSymbol #'thickness = #(magstep -4)
            \remove "Time_signature_engraver"
            \remove "Clef_engraver"
            \override KeySignature #'transparent = ##t
            \override KeySignature #'X-extent = #'(0 . 0)
        }
        {
            \clef "treble_8"
            \key a \major
                gis,16 a cis e a cis, e a gis, a cis e a cis, e a |

        }

}
