Clarify raw borrow expression precedence #1726
Description
On the Expression precedence section in the rust reference, I am assuming that raw borrow operators (&raw const and &raw mut) are grouped with regular borrow operators (listed as Unary & and &mut in reference) in terms of precedence? I think it would be good to get this clarified in that section. I can submit a PR if that's desired, but I am honestly not sure about its precedence myself.
