Incorrect formatting of [msg.sender]

[josojo]

Hello,

After running prettier on the following code:

contract Example {
    using SafeMath for uint256;
    
    struct BalanceState {
        uint256 balance;
    }

    mapping(address => mapping(address => BalanceState)) private balanceStates;
    function example(address token, uint amount) public {
        balanceStates[msg.sender][token].balance = balanceStates[msg.sender][token].balance.sub(amount);
    }
}

I get:

contract Example {
    using SafeMath for uint256;

    struct BalanceState {
        uint256 balance;
    }

    mapping(address => mapping(address => BalanceState)) private balanceStates;
    function example(address token, uint256 amount) public {
        balanceStates[msg.sender][token].balance = balanceStates[msg
            .sender][token]
            .balance
            .sub(amount);
    }
}

The formating of msg.sender is obviously incorrect.

I provided this minimal example over here in a repository, so that it is easy to reproduce:

A fix would be awesome! Prettier is a great tool
