OK So I've made the changes that I got replies about.

hunk ./Distribution/Misc.hs 82
-               | RankTwoTypes
+               | RankNTypes
hunk ./Distribution/Misc.hs 85
-               | PatternTypeAnnotations
+               | ScopedTypeVariables
hunk ./Distribution/Misc.hs 101
+               | NamedFieldPuns
hunk ./Distribution/Misc.hs 106
-               | HoodDebugging

I removed HoodDebugging since it's just a library and not really an
extension in NHC, and since it's not accessable via source code in

I think we'll leave them in; they don't take up much space, and if
people use them and they go away, then we can possibly detect when
they're build-depending on a particular version of GHC, and output a
warning if they're code starts using this deprecated feature.
Otherwise, people will just use the "options-ghc" field and we won't
be able to notice them.
