Comment #1 on issue 2575 by [email protected]: Ambitus is incorrect in the case
of semitone staves
http://code.google.com/p/lilypond/issues/detail?id=2575
I don't expect LilyPond to guess ahead, so I would only expect reasonably
correct results when using
\new Staff \with
{ \consists Ambitus_engraver
middleCPosition = #1 }
{
c' c''
}
\new Staff \with
{ \consists Ambitus_engraver
staffLineLayoutFunction = #ly:pitch-semitones }
{
c' c''
}
However, this "time-invariant" way of establishing the settings does not
actually produce a result different from the original example, and so
definitely a fix seems required.
