Line-width in Lilypond-book

[Hugo Leonardo Ribeiro]

Hi everyone,
I am trying to adjust the line width in a lilypond-book example, but
whatever I try, it always look like a ragged right style. What I want is
to stretch the line, in order to the chords places more distant one from
each other.
I searched in earlier messages and someone named Morton had the same
problem:

Graham said that this bug was fixed in 2.10.6.
I am using 2.12.1 and have this problem.

This is the latex code:

\begin{center}
\lilypondfile[noindent,line-width=10
\cm,staffsize=15]{exemplos/parte_4/cap01/exemplo01.ly}
\end{center}

This is the Lilypond code:

\version "2.12.0"

cima = {
\time 5/4
<<
\relative c''{a4 b c d e} \\
\relative c'{f4 g aes bes c} 
>>
\bar "||"

\time 3/2
\relative c' {<c e g b>2 <d fis a cis> <e gis b dis> }
\bar "||"

\time 4/2
\relative c' {<a d g>2 <c f bes> <b e a> <d g c> }
\bar "||"
}

\score {
        \new Staff \with { \remove Time_signature_engraver } << \cima >>
        \layout {
%               ragged-right = ##t
%               indent = 2.5\cm
        }
        \midi {
                \context {
                \Score tempoWholesPerMinute = #(ly:make-moment 60 4)
                }
        }
}


Thanks in advance.
