Okay thank you Julia.
So I can add something like this to the commit message?

"Replace the bitwise AND operator `&` with a modulo
operator `%` and decimal number to make the upper limit visible
and clear that we are doing indexes that are wrapped around the given number"?

You also said I should add a patch for the white space around binary operators.
I did it together because the changes were on the same line.
Should I still add a second patch for that change?
Thanks
