Horizontal spacing depends on stem 'direction

[Trevor Daniels]

I'd class this as an engraving nitpick, but we don't have that 
classification anymore.

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 "2.15.8"
\score {
 \relative c'' {
   \repeat unfold 6 { a4 a a a }
 }
}

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