			The 'check-whitespace' CI script exits gracefully if no base commit is provided or if an invalid revision is provided. This is not good because if a particular CI provides an incorrect base_commit, it would fail successfully. This is exactly the case with the GitLab CI. The CI is using the "$CI_MERGE_REQUEST_TARGET_BRANCH_SHA" variable to get the base commit SHA, but variable is only defined for _merged_ pipelines. So it is empty for regular pipelines [1]. This should've failed the check-whitespace job. Let's fallback to 'CI_MERGE_REQUEST_DIFF_BASE_SHA' if "CI_MERGE_REQUEST_TARGET_BRANCH_SHA" isn't available in GitLab CI, similar to the previous commit. Let's also add a check for incorrect base_commit in the 'check-whitespace.sh' script. While here, fix a small typo too.
