I think this is a behavior change. if (git_config(read_branch_desc_cb, &cb) < 0) was never true in practice, so the "return -1" was essentially dead code. You now return -1 when no value is found.

It probably doesn't matter, since all caller except fmt-merge-msg.c:add_branch_desc() ignore the return value, and if I read correctly, add_branch_desc does not need the test on the return value, as the then branch of the if does nothing if no value is found anyway.

But here again, I have to wonder why the function does not just return void.
