Occasionally I fall into a broken HTML and found -preparsed switch
very useful when deal with SortaSGML/TagSoup ^V key.
* More consistent docs for debugging of invalidly nested HTML:
important trace messages from actions on invalid tags now have '***' prefix
like "SGML: ... ***ignored" (well: illegal, forced, assumed, etc.),
-preparsed mode now better documented.
