New issue 1912 by brownian.box: Horizontal spacing depends on  
stem 'direction

It seems the horizontal spacing is slightly dependent on the stem  
direction. This can cause a score to mysteriously spread over an extra  
system when a single note with stem down is changed to one with stem up, if  
the original system exactly fitted the line width.

The following example demonstrates this by showing the slight difference in  
the two line lengths.

\version "2.15.12"
\score {
 \relative c'' {
   \repeat unfold 6 { a4 a a a }
 }
}

\score {
 \relative c'' {
   \repeat unfold 6 { c4 c c c }
 }
}
