 commit ddeb70b333a94990dbdf432303cb1f10f2d3062d

     Fix the behaviour of the unit unboxed tuple (# #)

     See Trac #5720: make the unit unboxed tuple (# #) behave uniformly
     with the unit boxed tuple ()

     This is actually a change in behaviour, but in a very dark corner,
     so I don't think this is going to hurt anyone, and the current
     behaviour is deeply strange.
