dynamics and polyphony

[Simon Dahlbacka]

It seems dynamics and polyphony does not mix very well, at least "out of the
box" as the snippet below clearly shows (with voice two overlapping the
dynamics of voice one)

%begin snippet
\version "2.10.0"

one = \relative c' {
   d\mf e\< f g\!
}
two = \relative c' {
   a a a a
}

mystaff = \new Staff {
   <<
   \new Voice = "one" {
       \voiceOne \one
   }
   \new Voice = "two" {
       \voiceTwo \two
   }
   >>
}

\score {
   <<
   \mystaff
   >>
}
% end snippet
