- Actually count the linefeeds in a the CDATA content.
- Don't call the endtag handler for an unmatched endtag (this makes
  the base class simpler since it doesn't have to deal with unopened
  endtags).
- If the __init__ method is called with keyword argument
  translate_attribute_references=0, don't attempt to translate
  character and entity references in attribute values.
