+
+ 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
+ traversing the list of overlays.
+
+ * buffer.h (struct buffer): Use an int for overlay_center.
+ (overlays_at, evaporate_overlays, recenter_overlay_lists)
+ (overlay_strings, fix_overlays_before): Use EMACS_INT for positions.
+
+ * buffer.c (reset_buffer, recenter_overlay_lists)
+ (adjust_overlays_for_insert, adjust_overlays_for_delete)
+ (fix_overlays_in_range, Fmake_overlay, Fmove_overlay)
+ (evaporate_overlays, init_buffer_once): Update use of overlay_center.
+ (overlays_at, evaporate_overlays, recenter_overlay_lists)
+ (overlay_strings, fix_overlays_before): Use EMACS_INT for positions.
+
+ * xdisp.c (fast_find_position): Remove unused var.

+ * minibuf.c (read_minibuf): UNGCPRO before returning.
+ (Ftry_completion, Fall_completions): Doc fix.
+
* alloc.c (live_float_p): Check that p is not past the `floats' array,
now that `floats' is not the last element of the struct any more.
