    CTest: Parse empty Git commits correctly
    
    Git's diff-tree format has no '\n'-terminated blank line at the end of
    its commit message body block if there are no diff lines.  Instead the
    message body is terminated by '\0' and there is no diff section.  Teach
    CTest to parse the format in this case.
