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