bug in snippet "Adding volta brackets to additional staves"

2021-02-28 Thread Jean-Charles Malahieude 
Revising the French translation of repeats.itely, I notice that the 
volta bracket doesn't appear in the third staff of the snippet with the 
master branch.


Just compare the two versions of the online documentation of NR-1.41.1 
where the bracket is present on v2.22, but not on v2.23.


Copying Dan who worked on this matter.

The performance length is 4 whole notes, but the third part has only
half that.  This is not what the image on the LSR means.

There is no \repeat music in the third staff, so why should there be
a volta bracket?

2.23 is handling this input more correctly.  I don't think this
snippet teaches anything more than the one entitled "Volta multi
staff".




I'm definitely not as good as expected with computation…

It might be wise to suppress it from the docs and LSR if not corrected.

Thanks for the report.  GIGO is my conclusion.  This is the source:

<<
  \new Staff { \repeat volta 2 { c'1 } \alternative { c' } }
  \new Staff { \repeat volta 2 { c'1 } \alternative { c' } }
  \new Staff \with { \consists "Volta_engraver" } { c'2 g' e' a' }
  \new Staff { \repeat volta 2 { c'1 } \alternative { c' } }

The performance length is 4 whole notes, but the third part has only half that. 
 This is not what the image on the LSR means.

There is no \repeat music in the third staff, so why should there be a volta 
bracket?

2.23 is handling this input more correctly.  I don't think this snippet teaches 
anything more than the one entitled "Volta multi staff".
