In that doc, under the heading "Declaring trace events", is a wordy
paragraph that looks like it was attempting to fill this need,
especially the last part.

Each event declaration will start with the event name, then its arguments,
finally a format string for pretty-printing. For example::
qemu_vmalloc(size_t size, void *ptr) "size %zu ptr %p"
qemu_vfree(void *ptr) "ptr %p"

It certainly has plenty of scope for improvement though !
