I switched from this:

[userdb function=get_cart nickname=shopping_cart]

to this:

[load-cart name=shopping_cart]

and it's merging but if the same item is in the current cart and
loaded from the saved cart then they end up as separate line items.
Can I have them either de-duplicated or incremented in quantity on the
same line?
