A simple solution would be to go back to using Devnull for the part
combiner's "null" Voice context; however, for it to work properly,
Staff would need to accept Devnull as a child. Devnull should perhaps
be added as an acceptable child of everything that accepts Voice and
NullVoice. I'm having trouble imagining unintended consequences of
that.

The point of Devnull is not to produce output. Some stuff is engraved
at Staff level (like time and key signatures) and if Devnull can be a
child of those, it can produce the respective output via those.

[issues:#5389] Partcombine: partcombine warns erroneously for unterminated slur

Good morning,

I've been reading up on partcombine recently and I wanted to try out a few examples from the documentation to help me really understand the command, however I get this error with one example:

From:

http://lilypond.org/doc/v2.19/Documentation/notation/multiple-voices#automatic-part-combining

Error:

warning: unterminated slur r2 g'4( f8 e) |

I have not modified the code at all, just copy and paste.

I thought it was due to some voice-issue but I can't figure out how to fix. Thanks for any help.

Code:

musicUp = \relative c'' {
  \time 4/4
  a4 c4.( g8) a4 |
  g4 e' g,( a8 b) |
  c b a2.
} % begin verbatim

musicDown = \relative c'' {
  g4 e4.( d8) c4 |
  r2 g'4( f8 e) |
  d2 \stemDown a
}

\score {
    <<
    \new Staff \with { instrumentName = #"Standard polyphony" }

      << \musicUp \\ \musicDown >>

    \new Staff \with {
      instrumentName = #"PartCombine without text"
      printPartCombineTexts = ##f
    }

    \partcombine \musicUp \musicDown

    \new Staff \with { instrumentName = #"PartCombine with text" }
      \partcombine \musicUp \musicDown
    >>

 \layout {
    indent = 6.0\cm
    \context {
      \Score
      \override SystemStartBar.collapse-height = #30
    }
  }
}
