I've committed a patch implementing grace autobeaming to
<URL:http://code.google.com/p/lilypond/issues/detail?id=3566>

This patch does not contain a regression test, and I debugged an
eternity to figure out why a single rest would not be enough to stop a
beam group from being formed.  I finally got smart and compared to the
normal autobeamer results, and, well, it's not sufficient to break off
beaming there either, so the behavior is consistent.

Now this issue is missing a regression test.  This thread contained
several scans and examples (also of not-beamed-through grace figures),
and you'll probably have your own ones.  Could you put together a few
measures exhibiting several of those cases for use in a regression test?

If you don't have the means of applying a patch and recompiling, just
write the stuff up in the way that you imagine it should look with a
working grace autobeamer.

That's the kind of diligence work I'm not particularly good at, so it
would be nice if you pitched in here.

Thanks
