+	* uniquify.el: overall speedup changes when using many buffers.
+	(uniquify-fix-item-base, uniquify-fix-item-filename,
+	uniquify-fix-item-buffer): Changed defmacro to defalias
+	(cosmetic change).
+	(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
