Replace the line:

  comment_expr = 
/^\s*#{regexp_quoted_comments[0]}(.*)#{regexp_quoted_comments[1]}/

With:

  # Quote any regexp characters
  regexp_quoted_comments = comment_strings.map {|string| 
Regexp.quote(string)}

  comment_expr = 
/^\s*#{regexp_quoted_comments[0]}(.*)#{regexp_quoted_comments[1]}/
