Feature: Git environment variables are respected and used instead of using the current working directory.


  Scenario Outline:
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-commit-hash is provided as "<from_commit_hash>".
    Then the Git history is clean.
    Given the GIT_DIR environment variable is set to the cloned repository.
    Then the Git history is clean.


    Examples:
      | repository                                  | checkout_commit                          | from_commit_hash                         |
