[project @ 2005-11-24 09:46:01 by simonpj]
A patch to the already-somewhat-delicate machinery that deals with
pattern-matching on unboxed tuples.  This patch deals with pattern
matches that can fail, e.g.
case f x of
  (# Just x, Nothing #) -> ...

The fix is in desugaring of HsCase (DsExpr.lhs).

The test is dsrun013
