Rtop: show directive fails on remapped operators

[Octachron]

Using #show on remapped operators prints the signature of the corresponding OCaml operator, not the remapped Reason operator. For instance, #show (^) prints the signature of (++):

#show (^)

let ( ^ ): (string, string) => string;

whereas

(^); 

• : (ref('a)) => 'a =

and requesting the signature of (++) itself fails:

#show (++)

Unknown element.
