Grace accidentals

[Erik Sandberg]

Hi,

When a grace notes occurs as the first note of a measure, it acts as if it 
would be the last note of the previous measure, when it decides whether it 
should display its accidental. E.g., in the following example, the first 
grace note does not get a sharp, while the second one does get a natural sign.

\score {
  \notes {ais1 | \grace ais8 ais1 | \grace a a }
  \paper {}
}
