[Haskell-cafe] ANN: haskell-src-exts-1.3.0

[Jose Iborra]

Brilliant !
This release promptly fixes an annoying bug I was about to report with
the pretty printing (not exact)  of infix function declarations like

 > instance Applicative (Either e) where
 >  pure = Right
 >
 >  Right f <*> Right x = Right (f x)
 >  Left  e <*> _       = Left e
 >  _       <*> Left e  = Left e

Thanks,
pepe
