Comment #20 on issue 630 by address@hidden: non-synchronized grace note makes  
voiceOne go stems down
http://code.google.com/p/lilypond/issues/detail?id=630

This is actually a bit of a dilemma here: the previous behavior was to do a  
revert+override when setting voice settings, and a revert afterwards.  For  
things like graces, which are intended to override the settings  
temporarily, the initial revert was wreaking havoc, and omitting the  
initial revert makes sense.  However, if one considers voiceOne and  
oneVoice as commands establishing an _absolute_ behavior, the  
pop-before-push semantics make some sense as well.

I will recheck my approach and see whether it is possible to differentiate  
this better.
