title: Tab key == 4 spaces and auto-indent after curly braces in Vim
body: <p>How do I make <a href="http://en.wikipedia.org/wiki/Vi" rel="noreferrer">vi</a>-<a href="http://en.wikipedia.org/wiki/Vim_%28text_editor%29" rel="noreferrer">Vim</a> never use tabs (converting spaces to tabs, bad!), makes the tab key == 4 spaces, and automatically indent code after curly brace blocks like <a href="http://en.wikipedia.org/wiki/Emacs" rel="noreferrer">Emacs</a> does?</p>
  
  <p>Also, how do I save these settings so I never have to input them again?</p>
  
  <p>I've seen other questions related to this, but it always seems to be a little off from what I want.</p>
