Fix bug #10159 with crashes in auto-complete package.

src/xdisp.c (next_overlay_string): Initialize it->end_charpos for
 the new overlay string.  Otherwise, the call to composition_compute_stop_pos
 in compute_stop_pos uses a wrong it->end_charpos value, and crashes because
 it runs off the end of the overlay string.
