Grace bug

[Erik Sandberg]

Hi,

I'm using 1.5.68 (waiting for the 1.6.0 .deb to be released). But I haven't 
seen this problem reported, so it might still be there:

If you override the flag-style of a grace note to normal, without reverting 
it afterwards, notes after the grace block will get slashes through their 
stems. Is this a bug, or is there a logical reason that it should be this 
way?

\score { \notes { \context Voice { 
  \grace {
    \property Voice.Stem \override #'flag-style = #'()
    c''8 % this gets flag-style = (unset)
  }
  c''8 % this gets flag-style = grace
}}}
