Hi Roberto,

The previous array had 255 element, not 256. The patch didn't change
that, so all the patch does, effectively, is remove explicit zeroing;
just as the commit message describes.

But yes, you're right, you'd need 256 elements to be able to index into
an array as any unsigned char. So maybe it *should* be 256.
