Re: [PATCH v3] var: add GIT_DEFAULT_BRANCH variable

Eric Sunshine [off-list ref] writes:

earlier in the thread (i.e. create a dummy repo and ask it for its
default branch)? Something like this (untested):

    (
        sane_unset GIT_TEST_... &&
        git init defbranch &&
        git -C defbranch symbolic-ref --short HEAD >expect &&
        git var GIT_DEFAULT_BRANCH >actual &&
        test_cmp expect actual
    )

So, the idea is to "observe" what the init command actually does,
and see if that matches the behaviour of the var command?

Sounds like a good way to ensure correctness to me.

Thanks.
