commit 913b3146541e203b2524e756b047b7f90be849b7
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Wed May 14 12:16:13 2014 +0200

    Avoid NondecreasingIndentation syntax in ghc-pkg
    
    This also makes ghc-pkg.cabal `default-extensions`-free
    
    NB: Printing this commit via `git show --ignore-all-spaces` shows the
        only non-whitespaces changes are in `ghc-pkg.cabal`
