Well, they are.

But in git-core the value is pulled into a single static. For a string its often a single static char*. So the config handle function is called up to 3 times for foo.bar, and the last one to be called is the one that finally set the value. They are read in the order I described above, so GIT_DIR/config has a chance to override any prior setting.

In JGit the RepositoryConfig object parses the other direction. Its a more classical "default" pattern, where if GIT_DIR/config doesn't have a foo.bar we call to another instance which had parsed ~/.gitconfig, and so on.

Either way produces the same result.
