(insert_1_both, insert_from_string_1)

Browse source 
(insert_from_buffer_1): Recalculate END_UNCHANGED in case the
insert happened in the end_unchanged region.  Otherwise, the
redisplay may be confused and duplicate the last line in the
buffer [seen after save-buffer when require-final-newline==t].
