    Export 'Showing' from Hoopl.Show
    
    GHC Trac user nimnul reports in
    https://ghc.haskell.org/trac/ghc/ticket/10540:
    
      Hoopl exports
    
        showGraph :: Showing n -> Graph n e x -> String
    
      But it doesn't export Showing. This doesn't make sense, as it's a
      user-supplied function. So to know what I should pass to showGraph I can only
      look at the source. :i Showing doesn't work.
    
      Below is a patch to export the innocent type synonym:
