I didn't mean to imply that it shouldn't generate those warnings,
just acknowledging that the warning serve to indicate that this
probably isn't "snippet-quality" code.

I was trying to reproduce the example .png given in the blog,
accessible at http://felixrosch.com/example.png.

That example shows two grouped staves, each with two horn parts
written on the same stem, as though they were a chord.  I didn't
know how else to merge the noteheads from two different voices
onto a single stem.  See opening disclosure.  I'll try chasing
down some of Xavier's clues.
