Flush the formatted text of pretty-printer PP onto the attached stream,

using XML escape sequences.
http://www.graphviz.org/doc/info/lang.html#html states:
special XML escape sequences for ", &, <, and > may be necessary in
order to embed these characters in attribute values or raw text
This doesn't list "'" (which would normally be escaped in XML
as "&apos;" or in HTML as "&#39;");.
Experiments show that escaping "'" doesn't seem to be necessary. */
