This test produces pseudo-collisions and tests git diff's behavior with them, and is therefore sensitive to the hash in use. Update the test to compute the collisions for both SHA-1 and SHA-256 using appropriate constants. Move the heredocs inside the setup block so that all of the setup code can be tested for failure.
