Comment (by ckoparkar):

 While looking through some old GitHub PR's, I found this
 [https://github.com/haskell/cabal/issues/1681#issuecomment-101175802
 thread] where 23Skidoo proposed this exact same idea before:

 >> Fuuzetsu: Right. I actually realised that we could have just one
 generic implementation in Cabal and Haddock could import that and feed
 args through it before doing Haddock-y stuff. It'd ensure consistent
 implementation which I believe is what we're after.
 > 23Skidoo: process or base are probably more appropriate places for this
 - I bet that getArgsWithResponseFiles could be generally useful.
