+
+ Change overlays_after and overlays_before so the overlays themselves
+ are linked into lists, rather than using cons cells. After all each
+ Lisp_Misc already occupies 5 words, so we can add a `next' field to
+ Lisp_Overlay for free and save up one cons cell per overlay (not
+ to mention one indirection when traversing the list of overlay).
+
+ * lisp.h (struct Lisp_Overlay): New field `next'.
+
+ * buffer.h (struct buffer): Change overlays_before and overlays_after
+ from Lisp lists of overlays to pointers to overlays.
+
+ * buffer.c (overlay_strings, recenter_overlay_lists):
+ Fix typo in eassert in last commit.
+ (unchain_overlay): New function.
+ (add_overlay_mod_hooklist): Use AREF.

+ (overlay_touches_p, overlay_strings, recenter_overlay_lists)
+ (fix_overlays_in_range, fix_overlays_before, Fmake_overlay)
+ (Fmove_overlay, Fdelete_overlay, Foverlay_lists)
+ (report_overlay_modification, evaporate_overlays, init_buffer_once):
+ Adjust to new type of overlays_(before|after).
+
+ * alloc.c (mark_object): Mark the new `next' field of overlays.
+ (mark_buffer): Manually mark the overlays_(after|before) fields.
+
+ * coding.c (run_pre_post_conversion_on_str):
