+       (uniquify-fix-item-unrationalized-buffer): Deleted: was the fourth
+       place in the item, but waas never used.
+       (uniquify-fix-item-min-proposed): New defalias: the fourth place
+       in the item is now used as cache for the porposed name.
+       (uniquify-rationalize-file-buffer-names): Move computation made on
+       newbuffile out of the loop, in the newbuffile-nd local var.  Use
+       dolist (cosmetic change).  Compute the proposed name for the most
+       common case and cache it in the fourth place in the item.
+       (uniquify-rationalize-file-buffer-names): Used to return a a list of
+       buffer whose name was changed, but that return value was never
+       used.
+       (uniquify-item-lessp): Replaces uniquify-filename-lessp, works on
+       the cached proposed name, does much less consing and is quicker.

+       (uniquify-rationalize-a-list): Use dolist (cosmetic change).  Do

+       (uniquify-get-proposed-name): Arguments changed, callers changed.
+       (uniquify-rationalize-conflicting-sublist): Explicitely reset the
+       uniquify-possibly-resolvable flag, which is no more bound locally.
