Sails is throwing the following when I run sails new api --without=views,session

$ sails new api --without 'views,session'                                                           
 Choose a template for your new Sails app:
 1. Web App  ·  Extensible project with auth, login, & password recovery
 2. Empty    ·  An empty Sails app, yours to configure
 (type "?" for help, or <CTRL+C> to cancel)
? 2

Reproduce the failure with sails new api --without=views,session and inspect sails-generate/lib/core-generators/new/before.js, the file named in the stack trace. Trace how the without option is parsed, then verify that the documented comma-separated values are accepted and that a generated app omits the requested features.
