- SF bug #853506: IP6 address parsing in sgmllib
  ('[' and ']' were not accepted in unquoted attribute values)

- cleaned up tests of character and entity reference decoding so the
  tests cover the documented relationships among handle_charref,
  handle_entityref, convert_charref, convert_codepoint, and
  convert_entityref, without bringing up Unicode issues that sgmllib
  cannot be involved in
