	Bug 492794 – Pasting external text at end of view yields wrong
	scrolling to mark

	* gtk/gtktextbuffer.[ch]:
	* gtk/gtktextview.c:
	Add a "paste-done" signal and use it to propelry scroll the
	view at the end of the pasted text in the case of an async
	paste. Patch by Ignacio Casal Quintero based on a patch by
	Yevgen Muntyan.
