Yes, but because it restates what the patch says instead of describing
the "why", it's at the wrong level of abstraction.

Starting from

    t7006: Use test_path_is_* functions in test script

    Modernize the test by replacing `test -e` instances with
    `test_path_is_file` helper functions, and `! test -e` with
    `test_path_is_missing`, for better readability and diagnostic messages.

I think what would make sense is to add a second paragraph describing
why the existing code uses ${if_local_config} and why what the new
code is doing is better.

Thanks,
