User/root password: Different behavior while checking it

[kobliha]

When you are entering the first user password, it lets you finish it and then it complains when the two entered passwords do not match, but when you try to enter the password for root, it starts complaining even before you enter the second one.

I'm not saying what is the better way, but at least the behavior should be unified.

We have no adapted the root password dialog yet (it should not be a pop-up after all). So we will take this bug into account when working on that.

Thanks!
