KHTML is much smarter about restoring form state now, taking into account element names and
	types instead of blindly blasting data by simple element ordering.  We encode the name
	and type at the front of the "state" strings that previously just held the value of the
	element.

	QString::endsWith() was just plain wrong.  Looks like it had some copied code, but was
	never really implemented.
