+ 
+       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.
+       (copy_overlays, reset_buffer, overlays_at, overlays_in)
+       (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):
+       * editfns.c (overlays_around):
+       * xdisp.c (load_overlay_strings):
+       * fileio.c (Finsert_file_contents):
+       * indent.c (current_column):
+       * insdel.c (signal_before_change, signal_after_change):
+       * intervals.c (set_point_both):
+       * print.c (temp_output_buffer_setup): Use new type for
+       overlays_(before|after).

        * buffer.c (report_overlay_modification): Don't run hooks while
