Invisible notes changing how width a staff is printed

Hi,

Currently I have the problem that I set a partitur with guitar cords
only visible as ChordNames and FretBoards. I use `\set chordChanges =
##t` to only set the name and fret board when the cord changes.

For the begin I use the full takt size as note size (in 2/4 = half
notes). That was looking good but then I changed the cords to encode the
takt I use with the guitar. (e2:m -> e4:m e8:m e:m) to have the correct
voice in MIDI.

Unfortunately, after that the staffs are broken into more lines than
possible.

Any help is appreciated.

Here is the relevant snippet:
   \version "2.18.2"
   \language "deutsch"
   \include "predefined-guitar-fretboards.ly"

   \header
   {
      title = "Roter Mond"
   }

   global =
   {
      \key c \major
      \time 2/4
      %\accidentalStyle Score.teaching
   }

   chordNamesChords = \chordmode
   {
      \global
      \germanChords
      \set chordChanges = ##t
      e4:m e8:m e:m | e4:m e8:m e:m | d4 d8 d | d4 d8 d | e4:m e8:m e:m | e4:m 
e8:m e:m | d4 d8 d | d4 d8 d |
      \repeat volta 2
      {
         g4 g8 g8 | g4 g8 g8 | d4 d8 d | d4 d8 d | c4 c8 c | c4 c8 c | e4:m 
e8:m e:m | e4:m e8:m e:m |
      }
   }

   classicalGuitar = \transpose a e \relative a
   {
      \global
      %\accidentalStyle Staff.teaching
      \easyHeadsOn
      a4 a | a2~ | a4 h8 c | h a g4 | a a a2~ | a4 h8 c | h a g4\break
      \repeat volta 2 { e'4 e | e2~ | e4 d8 e | d4. c8 | d4 d8 c | d4~ d8 c | 
a4 a8 g | a2 }
   }

   tenorSax = \transpose b, c' \transpose a e \relative a
   {
      \global
      \easyHeadsOn
      \transposition b,
      a4 a | a2~ | a4 h8 c | h a g4 | a a a2~ | a4 h8 c | h a g4\break
      \repeat volta 2 { e'4 e | e2~ | e4 d8 e | d4. c8 | d4 d8 c | d4~ d8 c | 
a4 a8 g | a2 }
   }
   verseOne = \lyricmode
   {
      \set stanza = "1."
      Ro -- ter Mond ü -- berm Sil -- ber -- see, Feu -- er -- glut wärmt den 
kal -- ten Tee.
      \set stanza = "1."
      Kie -- fern -- wald in der Nacht und noch ist der neu -- e Tag nicht er 
-- wacht.
   }
[...]
   chordsPart =
   <<
      \new ChordNames \chordNamesChords
      \new FretBoards \chordNamesChords
   >>

   classicalGuitarPart = \new StaffGroup \with
   {
      \consists "Instrument_name_engraver"
      instrumentName = "Git."
   }
   <<
      \new Staff \with { midiInstrument = "acoustic guitar (nylon)" }
      {
         \clef "treble_8"
         \new Voice = "noten"
         {
            \classicalGuitar
         }
      }
      \new TabStaff \with { stringTunings = #guitar-tuning }
      \classicalGuitar
   >>

   tenorSaxPart = \new Staff \with
   {
      instrumentName = "Tenorsax"
      midiInstrument = "tenor sax"
   }
   \tenorSax
[...]
   \score
   {
      <<
         \chordsPart
         \classicalGuitarPart
         \tenorSaxPart
         \leadSheetPart
      >>
      \layout
      {
         indent = 13\mm
      }
      \midi
      {
         \tempo 4=130
      }
   }

Any Idea, what I can do to just ignore the invisible cords in
calculation?

Regards
   Klaus
