This works perfectly. Thanks!

When I removed the \\, I got errors about clashing columns.  I'll check 
into the explicit voice instantiation thing.  For now I like the 
\oneVoice solution for this example.

The \oneVoice solution did not work for the example from GDP I'm working 
on, though.  The autobeaming still doesn't appear.  Here's the original 
code and then the fix I made for it.  In James' example, the \oneVoice 
fixed stem direction and autobeaming.  In this example, there was no 
problem with stem direction to begin with, just with autobeaming.  If 
you see a more elegant way please share :)

p.s. As I mentioned before, this example in the docs is not specifically 
aimed at multiple voices, so another solution would be to remove the 
second voice altogether.  It just bugs me when stuff doesn't work :)
