RFL: I think it's still called a stock dividend. I agreed with you that this is not dilutive. The price will not be readjusted to account for these shares.
Shorters (if there even are any) don't have to borrow stock from the other company. If a shorter is given the dividend, he just turns it over to the real owner of the shares he's borrowing. As for the naked shorter story here, IMO it's a myth. I've only seen one case of this, and the company had a very tiny o/s. The rest have all turned out to be due to heavy dilution.
