Proposal: sharing .git/config

Hi,

I have this itch where I want to share my remotes config between machines. In my fork, I should be able to specify where my upstream sources are, so remotes get set up automatically when I clone. There are also other things in .git/config that would be nice to share, like whether to do a --word-diff (why isn't it a configuration variable yet?) on the repository. The only problem is that I have no clue how to implement this: I'm currently thinking a special remote ref?
