I'm trying to push a patch that needs a supporting change to haddock. I've pushed the haddock change to the ghc-head branch of ssh://git@github.com/haskell/haddock.git, which is (according to 'packages') the relevant haddock upstream repo. But when I try to push the GHC patch, I get this message bash$ git push Counting objects: 45, done. Delta compression using up to 32 threads. Compressing objects: 100% (45/45), done.
