title: ESLint : Fast way to solve "Irregular whitespace not allowed"
body: <p>I'm trying to use ESLint to enforce a coding style on a project, and I have many <code>Irregular whitespace not allowed</code> errors  caused by code like this :</p>
  <pre><code>var a = b ||  10; //note the 2 spaces between || and 10
  if (a === 10)  {  // again, 2 spaces between ) and {
  </code></pre>
  <p>I haven't found any way to solve this problem easily for all my files.
  I think basic regex wouldn't work, as double spaces can be valid in some situations (column indentation of JSON object, indentation with soft tabs, strings).</p>
  <p>I tried tools, such as js-beautify, but didn't find any options to solve this problem. Is there a tool that could help me ?</p>
