title: starting Python IDLE from command line to edit scripts
body: <p>I've tried many variations of this command: <code>idle.py -e filepath</code>, but it simply starts IDLE like normal, not opening any extra windows for editing, and not throwing any errors.</p>
  
  <p>So how can I do the equivalent of opening IDLE, file>open>filepath via the command line (or perhaps even a Python module)?</p>
