When fsck_commit() identifies a problem with the commit, it should try to make it possible to continue checking the commit object, in case the user wants to demote the detected errors to mere warnings.
Note that some problems are too problematic to simply ignore. For example, when the header lines are mixed up, we punt after encountering an incorrect line. Therefore, demoting certain warnings to errors can hide other problems. Example: demoting the missing-author error to a warning would hide a problematic committer line.
