How do update and copy work if target selects a mix of objects and arrays?

Spec is currently unclear on that edge case:

• do nothing, or
• treat each selected target node according to its type.

To add some more context, this is the wording with have for Update, and similar for the #150 copy proposal (actions fields table):

If the target selects an object node, the value of this field MUST be an object with the properties and values to merge with the selected node. If the target selects an array, the value of this field MUST be an entry to append to the array.

We also have this wording below the table:

The result of the target JSONPath expression MUST be zero or more objects or arrays (not primitive types or null values).

I suggest that we add something along those lines below that last sentence:

Should the target JSONPath result in selecting two or more nodes, they MUST all either be objects or arrays.

Which I think would be pretty clear that if the selection result is mixed, that's an error.

Thoughts?

Thanks for the thumbs up. Put together #212 to address this.
