Automatic beaming of tuplets

[Nick Payne]

I'm trying to get tupletted sixteenth notes automatically beamed in 
groups of three in 3/4 time. The following beams the 16th notes in twos 
outside the tuplet, but inside the \times 2/3 {} it doesn't work. Can it 
be done without using manual beaming?

\version "2.13.4"

\relative c' {
   \time 3/4
   \overrideBeamSettings #'Voice #'(3 . 4) #'end #'((* . (3))
       ((1 . 16) . (2 2 2 2 2 2))
       ((1 . 32) . (8 8 8))
       ((1 . 64) . (16 16 16))
       ((1 . 128) . (32 32 32)))
   f16 a f a f a f a f a f a |
   \times 2/3 {
       e16 d' b' c,, e g e g a g c e a, c f f, c' a' |
   }
}
