* This method checks whether a header comment can be defined (i.e. whether
     * this is the first comment in the loaded file). If this is the case, it is
     * searched for the lates blank line. This line will mark the end of the
     * header comment. The return value is the index of the first line in the
     * passed in list, which does not belong to the header comment.
