interesting implementation detail of \partcombine

[Mike Solomon]

I just realized that when one uses spacer rests instead of full-measure rests in a voice that is being part combined, if there are full-measure rests in the other voice, those rests will be shifted up.

Not a biggie, but perhaps it should be documented if it is intended behavior or fixed to work like full-measure rests if intended behavior.  What do people think?

Cheers,
