grace/appoggiatura + key change bug

[David Bobroff]

This is a refinement of a bug report I recently made.  In the current
CVS version the following code (assuming it is "legal" input) produces
defective output.  The \grace note appears before the key change.  This
happens at key change points rather than at \bar "||" points as I
originally thought.
