The other two validations were about preserving an invariant ("file has
no tabs" & "file has no trailing whitespace") and more or less simple to
...whereas your suggestion seems problematic as it's difficult to know
whether a whitespace change to a Haskell program has semantic meaning;
for example, how should the script detect that the following whitespace

+++ main2.hs 2013-08-20 14:53:43.295960294 +0200

foo x = do
when x $ do
- putStrLn "doo"
+ putStrLn "doo"
...is actually a semantic change?
