title: jQuery as Composer dependency, why I'm forced to specify a version?
body: <p>I want to manage jQuery using Composer.</p>
  
  <p>I've added a custom repository and it's working fine. But why I need to specify a <code>version</code> and how to avoid this? The <code>url</code> will provide always the same stable version available and updating the version number all the time seems useless to me.</p>
  
  <pre><code>{
      "require": {
          "jquery/jquery": "*"
      },
      "repositories": [
          {
              "type": "package",
              "package": {
                  "name": "jquery/jquery",
                  "version": "1.9.1",
                  "dist": {
                      "url": "http://code.jquery.com/jquery.js",
                      "type": "file"
                  }
              }
          }
      ]
  }
  </code></pre>
