Partcombine: beaming

[Jean-Charles Malahieude]

Hello all,

While combining parts for a piano reduction (choral score), it appears 
that each time the first combine "voice" is lower than the other, beams 
are not "combined" :


\version "2.14.1"

VlnI = \relative c'' {
  a4. g8 f[ g a f]
}

VlnII = \relative c' {
  f4. g8 a[ g f a]
}

\score {
  \new Staff <<
    \set Staff.printPartCombineTexts = ##f
    \partcombine
    \VlnI
    \VlnII
  >>

  \layout { }
}
