First chord of measure too close to barline if it has a "grace note after"

Windows 7, GIT commit: d26a8df

1) new score
2) measure 2 (so it starts with bar line), note entry
3) add quarter note beat 1
4) add grace note after to the quarter note

Result: note moves close to barline

Cause is simple: the layout code treats grace notes like accidentals - allowing them to occupy space between barline and first chord - but this doesn't make sense for grace notes *after* the chord.
