Bug in DAO example - transferFrom() required to fail?

[DavidKDeutsch]

I have zero experience with solidity, but I'm pretty sure that the line(s) require (!t.transferFrom(_from, this, _value)); should not have the negation (!) in there. One of the code snippets uses a throw instead of a require, so my guess is the other lines used to use throw and the negation was accidentally left in there during the change to require.

The page I am referring to is at https://www.ethereum.org/dao.
