	a new variable to tell us if the old separator has been used.
	(InitLinkPatterns): The old separator, FS0, is set to \xb3 (the
	well-known superscript 3), and the new separator, FS, is set to
	\x1e, the ASCII control character RS, aka. RECORD SEPARATOR.
	(ReadFile): Convert data read from files from FS0 to FS if
	necessary when loading.
	(DoMaintain): More translating, some HTML changes.  Using the new
	field separator will not work for keep files, since new changes
	are just appended to the file.  The keep files must be updated,
	therefore.  This happens during maintenance, so make sure
	maintenance really gets run!  This also updates the recent changes
	log files (both old and current).

	(GetValidatorLink): Use $q->self_url for the validator link.
