The Git configuration should be a good one for Emacs development, and these 
commands (at least the transfer.fsckObjects part) should be done before the 
first 'git clone' command. That being said, you're right that people who aren't 
contributing to Emacs don't need a development-oriented Git configuration. So I 
separated the development-oriented commands from the fetch-and-build commands by 
installing the attached patch into master.
