Hi,

this is the fourth version of my patch series that addresses tests which
are specific to the "files" backend. There is only a single change
compared to v3, which is an improved commit message for the first patch.

Thanks!

         The t1300 test suite exercises the git-config(1) tool. To do so, the
    -    test overwrites ".git/config" to contain custom contents. While this is
    -    easy enough to do, it may create problems when using a non-default
    -    repository format because this causes us to overwrite the repository
    -    format version as well as any potential extensions. With the upcoming
    -    "reftable" ref backend the result is that Git would try to access refs
    -    via the "files" backend even though the repository has been initialized
    -    with the "reftable" backend, which will cause failures when trying to
    -    access any refs.
    +    test overwrites ".git/config" to contain custom contents in several
    +    places with code like the following:
     
    -    Refactor tests which access the refdb to be more robust by using their
    -    own separate repositories, which allows us to be more careful and not
    -    discard required extensions.

    +    cat > .git/config <<\EOF
    +    ...
    +    EOF
    +    ```

    +    Ideally, we would rewrite the whole test suite to not depend on state

    +    to be more robust by using their own separate repositories, which allows
    +    us to be more careful and not discard required extensions.
     
         Note that we also have to touch up how the CUSTOM_CONFIG_FILE gets
         accessed. This environment variable contains the relative path to a
