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.

Clarify all borrow operators in the precedence table
c5183c6 
This removes `&` and `&mut` and instead just links to the full grammar
for what the borrow operators are. There are many other variants, like
`&&` or `&raw`, and I didn't want to write all of them down. The
keywords after the `&&` are just modifiers, and are not really separate
things to be considered anyways.

Closes rust-lang#1726
