From: Derrick Stolee <dstolee@xxxxxxxxxxxxx> Add a test case that uses test_region to ensure that we are truly expanding a sparse index to a full one, then converting back to sparse when writing the index. As we integrate more Git commands with the sparse index, we will convert these commands to check that we do _not_ convert the sparse index to a full index and instead stay sparse the entire time.
