If a line ends with a space or tab and it is not a string, then raise a diagnostic and offer a fix to remove it.

I will use an interpunct (·) to represent trailling whitespace and a tab character (↹) to represent tabs. So this:

var i = 1;·
var j = 2;↹

Becomes

var i = 1;
var j = 2;

Multiple characters are removed as well.

So this:

var i = 1;·····
var j = 2;↹↹↹

Becomes

var i = 1;
var j = 2;
