bug#41946: 27.0.91; native json parsing: add :empty-object configuration

[yyoncho]

Sorry, for the short description. Here it is what I can do now:

(json-parse-string  "{\"a\":null}"
                    :object-type 'plist
                    :null-object :null-object)
=> (:a :null-object)

Here it is what I want to be able to do also:

(json-parse-string  "{\"a\":{}}"
                    :object-type 'plist
                    :empty-object :empty)
=> (:a :empty)

The purpose of this flag is to be able to distinguish json's null from json's empty object.

ATM this could be achieved only by binding null. I want to be able to bind an empty object as well.

Thanks,

Ivan

I don't think I understand the request.  Can you post more details,
please?  (Maybe it's some standard JSON feature that I'm not familiar
with?)
