It may be debatable if this is actually a bug or meant as a feature. IMO it is a bug.
If it is a feature, supply must at least be limited to GRAPHENE_MAX_SHARE_SUPPLY.

IMHO it's a bug and users must be restricted to borrow more than max_supply (thus current_supply must be always less or equal to max_supply) as was adjusted per concrete asset, at the same time while creating new asset users cannot create max_supply more than GRAPHENE_MAX_SHARE_SUPPLY.
