stemDown notehead colliding with sparse stemDown chord

[Robin Bannister]

\version "2.12.1" % regression: 2.10.33 and 2.8.8 are ok

dense = #(define-music-function (parser location mus) (ly:music?)
#{ s2  $mus $mus $mus $mus <d g'> 4 \noBreak #})

\score { \transpose c c' {
 \stemDown
 \dense e'16
 \dense d'16
 \dense c'16 % collision
 \dense b 16 % collision
 \dense a 16 % collision
 \dense g 16
 \dense f 16
 }
 \layout {
   indent = 0
   line-width = 120
   ragged-right = ##f
 }
}


Cheers,
Robin
