beams again

[David Bobroff]

Ok, now I have something in 3/16 and I want the beams to go the whole
measure (eighth notes are the longest value here) but I haven't found
the right syntax.  From searching the docs and mailing list (I couldn't
view the full messages, just the search result list) it seems that this
should work but it doesn't.
