title: Automatically add spaces around "=>"
body: <p>On SublimeText 3 I try to automatically add spaces before and after "=>"</p>
  
  <p>I try to add this in User Keybinding:</p>
  
  <pre><code>{ "keys": ["equals,&gt;"], "command": "insert_snippet", "args": { "name": "Packages/User/spacer.sublime-snippet" } } 
  </code></pre>
  
  <p>And this is my snippet:</p>
  
  <pre><code>&lt;snippet&gt;
  &lt;content&gt;&lt;![CDATA[ =&gt; ]]&gt;&lt;/content&gt;
  &lt;/snippet&gt;
  </code></pre>
  
  <p>But it's not working.</p>
