Re: voltaOnThisStaff not working as expected

[Mats Bengtsson]

It seems that this property has been removed in the implementation and
that the Volta_engraver by default has been moved to the Score context
(I seem to recall that I proposed a similar solution many years ago).
So, to get volta brackets on the top of a stave in the middle of the score,
you should instead add the Volta_engraver to it, see the regression test
called volta-multi-staff-inner-staff.ly

\score { <<
 \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' } }
>> }

Unfortunately, the manual (and the documentation of voltaOnThisStaff in
scm/define-context-properties.scm) were not updated correspondingly.
