clamp the value to [lower...upper-page_size] instead of only

	* gtk/gtkadjustment.c (gtk_adjustment_set_value): clamp the value
	to [lower...upper-page_size] instead of only [lower...upper].

	* README: add note about this change.

	While this fix is correct and should have been there forever, it
	has the potential to break some corner cases, however these cases
	would set page_size to a value != 0 which suggests they want it
	honored.
