Thank you.  In my example, the NullVoice is inside a Staff, and the NullVoice
contains the very same notes as the displayed Voice, so I don't think that
passage in the NR explains the problem.

I am also following the NR on the use of accidentalStyle:

"There are many different conventions on how to typeset accidentals.
LilyPond provides a function to specify which accidental style to use.
This function is called as follows:
     \new Staff <<
       \accidentalStyle voice
       { ... }
>>
The accidental style applies to the current Staff by default (with the
exception of the styles piano and piano-cautionary, which are explained
below)."
