abc2midi bug: though grace notes only contain notes, the syntax allows
you to substitute chords for grace notes. For example,
X:1
T:acc
M:4/4
L:1/4
K:G
[DF]|E {[bc]}B cd|D4|
The function applygrace_new (in store.c) was modified so that the two notes
in the chord [bc] are treated as if they were one note. Otherwise
the measure would be too short (B is shrunk to make room for b and c)
and there could be a loss of synchronization between the voices.
