title: Insert spaces around binary operators
body: <p>I've statements such as these:</p>
  
  <ul>
  <li><code>someVariable=someOtherVariable</code></li>
  <li><code>if(oneVariable&gt;otherVariable)</code></li>
  </ul>
  
  <p>No spaces around the operators makes it difficult for me to understand the code. I would like to insert spaces around <code>=</code> and <code>&gt;</code> so that the statements look like these:</p>
  
  <ul>
  <li><code>someVariable = someOtherVariable</code></li>
  <li><code>if(oneVariable &gt; otherVariable)</code></li>
  </ul>
  
  <p>So, basically if there are no spaces around <code>=</code> or <code>&gt;</code> insert spaces.</p>
  
  <p>How do I achieve this using substitution command?</p>
