.jshintignore is not working

[paladox]

If you have a .jshintignore file and you had a setup like this

    jshint: {
        options: {
            jshintrc: true
        },
        all: [
            '**/*.js'
        ]
    },

and your .jshintignore file looked like this

libs/jquery.browser.js
libs/jquery.dynatree.js
libs/jquery.fancybox.js
libs/select2.js
libs/SF_maps.js
node_modules/
vendor/

The .jshintignore file is ignored and the js that was supposed to be ignored is tested and brings back alot and alot of js errors because of node_modules folder.

Please fix this so .jshintignore is processed and ignores the folders and files correctly please.
