These abbreviated object names hardcode the use of SHA-1, but the code is tested in repositories that use SHA-256 as well. As you are creating four commits with distinct timestamps, I think you can simply filter out the object name part for comparison, perhaps like: redact_blame_output () { sed -e 's/\([^]*\)\([0-9a-f]*\) /\1HASH /' } test_expect_success 'git blame --since=...'

Given that there does not seem to be any clock skew in the history being tested, I am wondering if this new test file should even be a part of the topic. Thanks.
