Fix bug that created negative-length intervals.

* intervals.c (merge_interval_right, merge_interval_left):
Do not zero out this interval if it is absorbed by its children,
as this interval's total length doesn't change in that case.  See
<http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
