Correct parantheses for arithmetic unary minus

[Zerseu]

Please correct me if I'm wrong, but shouldn't double negation of x yield "-(-x)"?
Instead it returns "--x".

The following statement fails:
Assert.AreEqual(Expression.Negate(Expression.Negate(Expression.Parameter(typeof(double), "x"))).ToReadableString(), "-(-x)");

Hi!

The two look to produce the same result (see this fiddle) so I think it's just a question of coding style. The library generally minimises use of parentheses.

Thanks for the feedback :)
