  * Fix Trac #2358: 1-tuples in Template Haskell
  
  fons points out that TH was treating 1-tuples inconsistently.  Generally
  we make a 1-tuple into a no-op, so that (e) and e are the same.  But
  I'd forgotten to do this for types.
  
  It is possible to have a type with an un-saturated 1-tuple type
  constructor. That now elicits an error message when converting from
  TH syntax to Hs syntax
