However, that is not necessarily true. We may be in a subdirectory. Or .git may be a gitfile. Or the environment variable GIT_DIR may be set. To remedy this situation, we just refactored the way setup_git_directory() discovers the .git/ directory, to make it reusable, and more importantly, to leave all global variables and the current working directory alone. Let's discover the .git/ directory correctly in read_early_config() by using that new function. This fixes 4 known breakages in t7006.
