Aargh! Clearly I haven't had enough coffee today. I still think it's
true that it should be "tremolo 2" -- and without the manual beams it is
typesets correctly though not beamed the way you want. But the example
I showed with the manual beams is of course completely wrong! It's not
tremolo.
Sorry to be so daft.
