[PATCH 01/12] t6038 (merge.renormalize): style nitpicks

[Jonathan Nieder <jrnieder@gmail.com>]

Some tweaks to simplify adding and running tests.

 - Use test_tick for predictable, sort of realistic commit dates;

 - Use test_cmp as "test_cmp expected actual" --- some crazy
   content that was not expected should cause the test to fail;

 - Remove and re-add all files at the start of each test so the
   worktree is easier to think about;

 - Avoid using cat where not necessary for clarity.
