0c16dfed70 * intervals.c (adjust_intervals_for_insertion): Initialize `newi' 
with RESET_INTERVAL.
* buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
Remove duplicated buffer name initialization.

13c379eed0 Do not avoid creating empty evaporating overlays (Bug#9642). 
* buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
That is, do not delete an evaporating overlay if it becomes
empty after its bounds are adjusted to fit within its buffer.
This fix caused other problems, and I'm reverting it until we get
to the bottom of them.

89a438bd86 Do not create empty overlays with the evaporate property (Bug#9642). 
* buffer.c (Fmove_overlay): Delete an evaporating overlay
if it becomes empty after its bounds are adjusted to fit within
its buffer.  Without this fix, in a nonempty buffer (let ((o
(make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
yields an empty overlay that has the evaporate property, which is
not supposed to happen.

a041960a7c Improve ralloc.c interface checking. 
See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
* buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
(r_alloc_free) [REL_ALLOC]: Move decls from here ...
* lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
[REL_ALLOC]: ... to here, to check interface.
* m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
Remove decls.  This fixes an "It stinks!".
