What if somebody makes an attack where they can choose the size and then find a collision?

  Like the two files on the linked page?

    The two files on the linked page were both full of junk data. I suspect that those files being of the same length isn't the norm.

      I would bet that a fixed size M' is part of the attack.

      Why wouldn't it be the norm? If they're able to make files of the same length, other attackers can make files of the same length too.
