Solve the following python programming problem given the following code:
def _auto_link_urls(text, **href_attrs) : 
    def handle_match(matchobj) : 
        all = matchobj.group () 
        (before, prefix, link, after) = matchobj.group (1, 2, 3, 4) 
        if re.match ('<a\\s', before, re.I) : 
            return all 
text = literal ((prefix + link)) 
        if (prefix == 'www.') : 
            prefix = 'http://www.' 
a_options = dict (href_attrs) 
        a_options ['href'] = literal ((prefix + link)) 
        return ((literal (before) + HTML.tag ('a', text, ** a_options)) + literal (after)) 
return literal (re.sub (AUTO_LINK_RE, href_attrs, text)) 

    
    

    Fix the buggy line: return literal (re.sub (AUTO_LINK_RE, href_attrs, text))
