Solve the following python programming problem given the following code:
def _preprocess(config_string) : 
    'Convert a raw config into a form that preserves comments etc.' 
    results = ['[__COMMENTS__]'] 
    counter = itertools.count (0) 
    section_re = re.compile ('^(\\[[^\\]]+\\])\\s*(.+)$') 
    blank_line_re = re.compile ('^\\s*$') 
    comment_re = re.compile ('^(#|;)') 
    inline_comment_re = re.compile (' ;') 
    def newlines(match) : 
        return ('__BLANK%d__ =' % next (counter)) 
def comments(match) : 
        if (match.group (1) == '#') : 
            return ('__HASH%d__ =' % next (counter)) 
else : 
            if (match.group (1) == ';') : 
                return ('__SEMICOLON%d__ =' % next (counter)) 
def inlinecomments(match) : 
        return ('
__INLINE%d__ =' % next (counter)) 
def sections(match) : 
        return ('%s
__SECTION%d__ = %s' % (match.group (1), next (counter), match.group (2))) 
for line in config_string.splitlines () : 
        line = blank_line_re.sub (newlines, comment_re) 
        line = section_re.sub (sections, line) 
        line = comment_re.sub (comments, line) 
        line = inline_comment_re.sub (inlinecomments, line) 
        results.append (line) 
return '
'.join (results) 

    
    

    Fix the buggy line: line = blank_line_re.sub (newlines, comment_re)

#Here is Python program to fix the buggy line: line = blank_line_re.
