Comment 4 for bug 1822736

I followed Tom's REPRODUCTION test, and got exactly what Tom said I would.
I can confirm the issue with 256 character passwords.
(I used `wc` to count characters in my buffer)

I could set the 256 character password (I used it with a backspace to enter the old password, so it was only 1 character longer) but it wouldn't then let me use it for the next `sudo whoami`.
