Missing backticks in error message

The code

x `f` y = x x
(&) x y = x x

gives errors with missing backticks and parentheses:

A.hs:1:13:
    Occurs check: cannot construct the infinite type: t1 = t1 -> t0
    In the first argument of `x', namely `x'
    In the expression: x x
    In an equation for `f': x f y = x x
                            ^^^^^

A.hs:2:13:

                            ^^^^^
