title: Apache Commons CLI: how to prevent using short-name for options?
body: <p>In the Apache Commons CLI lib, is it possible to bypass the usage of short-name, thus forcing the user to use the long name?</p>
  
  <p>usually, options are defined like this:</p>
  
  <pre><code>new Option("u", "username", true, "automatic user name")
  </code></pre>
  
  <p>I would like to forbid the use of "u". But if I replace it with <code>null</code> or empty string, there are Exceptions...</p>
  
  <p>Why this requirement? I would like all my options to be only in the form --optionName=optionValue because some parts of my app are Spring Boot and Spring Boot recognizes by default options in this format.</p>
  
  <p>Additionally, for consistency amongst devs and users and to simplify the documentation, I find it better if we have a unique way to use an option instead of 2.</p>
