The scripts never commit. In fact, they only have read access to the remote
repository. Commits are only ever done by humans manually.

So it's going to be something like this:

  git fetch origin
  if [ git diff -s master origin/master ]
    git stash
    git merge -ff master
    git stash pop
  fi

Unfortunately, the return code of git-diff don't seem to indicate whether they
have diverged. And git-status don't seem to have an option to specify "remote
is ahead of me". How would I properly check whether a merge is actually needed?
