	* gtk/gtktextview.c (changed_handler): Correctly keep the same
	text on the top of the screen, considering that the changed region
	may have overlapped the first paragraph. Should fix msw's "text
	widget scrolled to wrong place on map" bug, and probably some
	other scrolling cases as well.
	(gtk_text_view_set_scroll_adjustments): start adjustments at 0.0,
	instead of some random value

	* gtk/gtktextview.c (gtk_text_view_class_init): actually override
	grab_focus, so #59708 is really fixed
