+	The filter set of function is used to format message text for
+	display. The message text gets converted from unicode to the
+	display character set, and excessively long lines get truncated to
+	some reasonable value.
+
+	Special characters: <, >, &, and " get replaced by their HTML
+	entities.
+
+
+	filter(ptr, cnt) - repeated calls to this function are used to
+	supply text being filtered.
+
+	filter_end() - is called when the end of the text being filtered
+	is reached.
