This will make counterparty to use the last issuance description for the asset

See CounterpartyXCP/Forum#109 (reply in thread). The copying of the last description is problematic by itself, so I'm not sure we should continue working on the current approach when we are already discussing a deeper solution. Why not wait for that?
