  * Refactor Haddock options
  
  This patch renames the DOC_OPTIONS pragma to OPTIONS_HADDOCK. It also
  adds "-- # ..."-style Haddock option pragmas, for compatibility with
  code that use them.
  
  Another change is that both of these two pragmas behave like
  OPTIONS_GHC, i.e. they are only allowed at the top of the module, they
  are ignored everywhere else and they are stored in the dynflags. There is
  no longer any Haddock options in HsSyn.
  
  Please merge this to the 6.8.2 branch when 6.8.1 is out, if appropriate.
