lint of unnecessary parentheses around `if` condition may case error

[bravomikekilo]

when unnecessary parentheses is removed, may lack a whitespace between if and expr.

example
if(is_prime) {println!("hello")};
while be replaced to
ifis_prime {println!("hello")};

Maybe we should replare (expr) with a pair of whitespace around expr, instead of just expr;

I am working on it.

Previous code
if (fee > 4) {
stake_pool.fee = 4;
} else {
stake_pool.fee = fee;
}

Updated code

if fee > 4 {
stake_pool.fee = 4;
} else {
stake_pool.fee = fee;
}
