+Hi\r
+\r
+I agree with this cycling approach but I think it needs to be per\r
+message rather than per buffer. I attach a rather hacky attempt at this\r
+below: on minimal testing it seems to work. But the lisp is really a bit\r
+gross. In particular I have no idea if I should be escaping the message\r
+ids (so this could break in unfortunate/insecure ways)\r
+\r
+Best wishes\r
