chord fingerings and octavation

[Daniel Leidisch]

Hello,

this is my first post at lilypond-user. I am using lilypond since a
few days and there are some minor problems I could not solve yet:

I am trying to print four V-I progressions for an article on my
homepage:


\version "2.10.0"

<<
        \chords { g2:7 c g:7 c g:7 c:maj7 g:7.9.13 c:6.9 }

        \relative c'' {
                        #(set-octavation 1)
                        <g d'f b>2^\markup \fret-diagram-terse #"x;x;5;7;6;7;"
                        <g c e c'>^\markup \fret-diagram-terse 
#"x;x;5-(;5;5-);8;"
                        <g b f' g>^\markup \fret-diagram-terse #"x;10;9;10;8;x;"
                        <c, e' g c>^\markup \fret-diagram-terse 
#"8-(;10;10;9;8;8-);"
                        #(set-octavation 0)
                        <g f' b d>^\markup \fret-diagram-terse #"3;x;3;4;3;x;"
                        <c e b' e>^\markup \fret-diagram-terse #"x;3;2;4;5;x;"
                        <g f' b e a>^\markup \fret-diagram-terse 
#"3;x;3;4;5-(;5-);"
                        <c e a d g>^\markup \fret-diagram-terse 
#"x;3;2-(;2-);3-(;3-);"
        }

1. As you can see, the chord fingerings are crossing the octavation
bracket. What could I do about that?

2. Is it possible to have the fingerings at the same height? It looks
a bit jagged to me, I would prefer all the fingerings at the level of
the highest one.

3. How could I insert straight lines to show the voice-leading? I would
like to have a line from h to c in the first bar, for example.


I tried to read those up myself, but I could not find the solution.

Thanks

Daniel
