another grace bug in 2.13?

[Paul Scott]

The presence of a grace note seems to change the stem directions in 
parallel music in at least 2.13.6 and 2.13.7.  The stem on the last B 
should go up.  Is this related to bug 385?  I'll file it if it's really 
a bug.


\version "2.13.7"

    \new Staff{
      \relative c'' {
        << { a2 b } \\ { R1 } >>
        << { \acciaccatura{ g8} a2 b } \\ { R1 } >>
      }
    }
  >>
}

Thanks,

Paul Scott
