Comment #1 on issue 3149 by [email protected]: Extra leading repeat sign
with leading rest and lyrics
http://code.google.com/p/lilypond/issues/detail?id=3149
a simple solution to this problem - I don't think it is a bug since
LilyPond simply adds what has been asked for and the Lyrics with \lyricsto
or \set associatedVoice only get the timing when they are merged to a voice
- is to add
\once \omit Staff.BarLine (with 2.17.??) or
\once \override Staff.BarLine #'stencil = ##f (before)
wherever a \repeatVolta doesn't coincide with the bar line placing of the
associated voices (or staves?) (can this be automated?)
one could discuss if the command \repeat volta in Lyrics should be
restricted this specific context and should _not_ be collected to the Score
context.
