grub password seems to be off by 1

[Scott Spurrier]

Hello,

I have a customer issue where the customer is trying to use a 32 
character password to secure grub.  The grub password does not allow 32 
characters...  It only allows 31 + null.  Does anyone know why 32 
characters were chosen to be the maximum for the password option and is 
there any plans to extend this to more characters in the future?

Thanks in advance,
-Scott
