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.
