Elisp is pretty liberal on what it allows as symbol names.

You didn't answer the important question:

I can change %cursor-marker% to have a symbol name that's nicer for
clojure to cope with. But it would be an interim solution, only. I
really want to see this fixed in Clojure.

At the moment, the Clojure backend does not correctly implement parsing
the protocol.
