+*** The function `frame-or-buffer-changed-p' now lets you maintain
+various status records in parallel.

+It take a variable (a symbol) as argument.  If the variable is non-nil,
+then its value should be a vector installed previously by
+`frame-or-buffer-changed-p'.  If the frame names, buffer names, buffer
+order, or their read-only or modified flags have changed, since the
+time the vector's contents were recorded by a previous call to
+`frame-or-buffer-changed-p', then the function returns t.  Otherwise
+it returns nil.
+
+On the first call to `frame-or-buffer-changed-p', the variable's
+value should be nil.  `frame-or-buffer-changed-p' stores a suitable
+vector into the variable and returns t.
+
+If the variable is itself nil, then `frame-or-buffer-changed-p' uses,
+for compatibility, an internal variable which exists only for this
+purpose.
