What if we create a ../.gitconfig like ../.gitattributes, that is loaded before .git/config? With loads of warnings in the documentation about what *NOT* to put in here, any platform specifics and your own risk. The code in config.c would look like the following, with obvious updates to documentation and the test suite, so it's not fully baked yet. So far, I don't have a solution to the chicken-and-egg problem, other than this. However, if I'm barking up the wrong ballpark...
