Add a documentation warning to ts_headline() pointing out that, when working with untrusted input documents, the output is not guaranteed to be safe for direct inclusion in web pages. This is because, while it does remove some XML tags from the input, it doesn't remove all HTML markup, and so the result may be unsafe (e.g., it might permit XSS attacks). To guard against that, all HTML markup should be removed from the input, making it plain text, or the output should be passed through an HTML sanitizer. In addition, document precisely what the default text search parser recognises as valid XML tags, since that's what determines which XML tags ts_headline() will remove.
