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.
