    When copying a single item:

    - object is copy of item

    - event.object is copy of item

    - event.original is original item

    Both copies have not been added to an acquisition context yet.

    When copying a folder that has sub folders with content, like
    folder/sub/doc, and pasting it to the same location so the origal
    and pasted folders are at the same level, this event is also fired
    with:

    - object is copy of doc, with physical path copy_of_folder/sub/doc

    - event.object is copy of folder, with physical path copy_of_folder

    - event.original is the original folder

    - sub is nowhere to be seen...

    Luckily we can use physical paths in that case.
