Grace note synchronization can also lead to surprises. Staff
notation, such as key signatures, bar lines, etc., are also
synchronized. Take care when you mix staves with grace notes and
staves without, for example,
<< \new Staff { e4 \bar "|:" \grace c16 d4 }
\new Staff { c4 \bar "|:" d4 } >>

This can be remedied by inserting grace skips of the corresponding
durations in the other staves. For the above example
\new Staff { c4 \bar "|:" \grace s16 d4 }
Is this no longer true?
Perhaps I was unclear, but my example represents an instrument part in
a full score, and I want to use the same source for both the full
score and the part.
