I was not aware of that.  Searching the NR for \accidentalStyle, I found only 
examples using Score, StaffGroup, and kinds of Staff.

I’ve found by experiment that if I remove Accidental_engraver from Staff and 
add it to Voice (& NullVoice), then I can use \accidentalStyle Voice.whatever 
to set the accidental style per voice.  Unfortunately, I have not figured out 
how to get what I want using that.

It seems to me that what I am looking for is not a per-voice accidental style, 
but a per-staff accidental style using a subset of the voices as input.  I *do* 
want the extra accidentals produced by the interaction between two NullVoices 
when the Accidental_engraver is in the Staff, but I *don’t* want interference 
from the part combiner’s voices in the same staff.
