Thanks for the explanation.

Unfortunately, this is not acceptable.  I still wonder whether it is
possible to make

  << { ... } \\ { } >>

equivalent to

  { ... }

this is, to prevent creation of \voiceOne and \voiceTwo at all.  I can
imagine that this is handled as a special exception to the normal
parsing rules -- the assumption is of course that an empty group
within << >> isn't used for other purposes.

On the other hand, making an empty \quote expand to a special Grob
which simply resets the vertical rest positions of the other voice(s)
to the default is probably better from a syntactical point of view.
