I'm totally cool with this JSLint error. How can I tolerate it? Is there a flag or checkbox for it?

You get it when you do stuff like:

v && arr.push(v);

as opposed to:

if (v) {

    arr.push(v);

}

Both do the same exact thing. If you put:

window.test = function(v) {

    'use strict';

    var arr = [];

    if (v) {

        arr.push(v);

    }

    return arr;

};

into the minifier it minifies down to this anyway:

window.test=function(a){var b=[];a&&b.push(a);return b};
