Documentation
Transient prefix command.
Each transient prefix command consists of a command, which is
stored in a symbol's function slot and an object, which is
stored in the transient--prefix property of the same symbol.
When a transient prefix command is invoked, then a clone of that
object is stored in the global variable transient--prefix and
the prototype is stored in the clone's prototype slot.
