Log message:
	It is possible for ResolveNew to be used to insert a sublink into a
	subquery that didn't previously have one.  We have traditionally made
	the caller of ResolveNew responsible for updating the hasSubLinks flag
	of the outermost query, but this fails to account for hasSubLinks in
	subqueries.  Fix ResolveNew to handle this.  We might later want to
	change the calling convention of ResolveNew so that it can fix the
	outer query too, simplifying callers.  But I went with the localized
	fix for now.  Per bug report from J Smith, 20-Oct-03.
