PATCH: loop bodies containing do..end blocks

[Doug Kearns]

Loop bodies containing do...end blocks such as the example below were
highlighted incorrectly. I can't see any reason why rubyDoBlock and
rubyCurlyBlock shouldn't be contained here.

for th in threads
  Thread.start(th) do |t|
    t.join
    @wait_queue.push t
  end
end
