Steve D continues:

Yes, the error message disappears with LilyPond 2.11.13. Thank you so
much Han-Wen.

And Joe, thank *you* so much for the suggestion to move the Tie_engraver
from the default Voice context to the Staff context instead. So far,
working with staves in a PianoStaff context, your suggestion is working
brilliantly, although I have only begun to test it and the piano piece
I'm working on now will really stress-test the technique I believe,
because it has many of these temporary splitting of the notes of the
right or left hand into two or more voices per hand, often for just a
fraction of a measure or spanning just parts of two or more measures.

If this technique (removing the Tie_engraver from the Voice context to
the Staff context) continues to work well, and if any bugs it causes can
be fixed or sponsored to fix, then this is an incredibly good solution
to the problem of temporary, non-formal, intermittent voices that often
occur in the notated music of polyphonic instruments such as piano. It
*greatly* simplifies the LilyPond code in such circumstances, and I am
personally very excited and enthused about the results so far.

Thank you Joe (Neeman), and thank you Han-Wen and other developers.
