Fwd: Cue notes included in ambitus

[Simon Albrecht]

Hello,

Patrick reported the problem below on ly-user and I think this is 
unintended behaviour deserving a tracker issue. Parts are less common 
with vocal music than with instrumental music (since often one has a 
vocal score with piano reduction anyway), but not uncommon, so the 
problem pertains also to what I consider to be the main use case for 
ambitus.

Yours, Simon

Consider the following snippet:

\version "2.19.17"

music = \relative c'' {
      \clef treble
      \new CueVoice { \set instrumentCueName = "Bass" }
      \cueDuringWithClef #"Bass" #DOWN #"bass"    R1
      g4 a b c
}

Bass = \relative g {
      \clef bass
      g,2 d'
}
\addQuote "Bass" \Bass

\score {
    \new Staff {  \music }
    \layout { \context { \Staff \consists "Ambitus_engraver" }     }
}

which produces the following printed output:


The ambitus clearly includes the cue notes.  Since the purpose of the 
ambitus is to allow performers to determine if the music matches their 
capabilities, it doesn't seem that the cue notes should be included in 
the ambitus determination since the performer won't be playing the cue 
notes.
