excludeFromFile: '.jshintignore' does not support glob format

[johnkchiu]

My .jshintignore file is actually a list of glob formats:

public/js/lib/**/*.js
public/components/**/*.js
public/js/lib/vendor/**/*.js
public/js/portal/bower_components/**/*.js
public/js/portal/lib/common/*.js
public/js/portal/lib/vendor/*.js
public/js/portal/components/**/*.js
public/js/portal/widgets/validateForm.js

This doesn't work because it's converted into a set of regex, which is not correct.
