JSHint ignores the `indent:` option hwen it's passed in globally

testcode.js

// contrived example. This file uses 3 spaces for indentation
function doStuff() {
   console.log("Stuff!");
}

testrunner.js

#!/usr/bin/env node

var fs = require('fs'),
    util = require('util');

var jshint = require('jshint').JSHINT;

var src = fs.readFileSync('./testcode.js').toString();

var success = jshint(src, {indent: 4});

if (success) {
    util.puts("The file passed");
} else {
    util.puts("The file failed JSHint with the following errors:");
    jshint.errors.forEach(function(err){
        if (err) { // sometimes there's a null at the end of the errors list
            util.error(util.format("\n%s\n%s\nline:%d, character:%d", err.reason, (err.evidence || '').trim(), err.line, err.character))
        }
    });
}


// expected behavior is an error about onluy using 3 spaces to indent
// actual behavior is that the scripts outputs "The file passed"
