[PATCH 10/11] t1312: create read/write test

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <stolee@gmail.com>

This new test will be extended in the future to ensure that multiple
commands that execute in order update the configuration state enough to
reflect new written values as we read them in later commands.
