About that I'm trying to come up with a way of make Undo operation
generic, so I need to understand linking code, since delete operation is
kinda explained in [https://bugzilla.gnome.org/show_bug.cgi?id=657974]
I saw the linking code is adding to the primary persona of the main
contact the details from the other one, or, if not main persona is
founded in both contact, then a new one is created.
Why I can't see is where you delete the secondary Contact object, cause
as far as I see, there's no deletion of the persona, not removing the
details either (thinking that the persona could remove itself when not
details got left).

Can u share some inside into this ?

Thxs in advance.
