title: Bower install from URL gives blank folder
body: <p>I'm using bower (v. 1.3.5) to pull in my Front-End JS dependencies, and I want to depend on this: <a href="https://github.com/dcneiner/Downloadify" rel="nofollow">https://github.com/dcneiner/Downloadify</a></p>
  
  <p>It doesn't have its own bower.json so I'm referencing by URL in MY bower.json:</p>
  
  <pre><code>  "dependencies": {
      "jspdf": "~1.0.272",
      "downloadify": "https://github.com/dcneiner/Downloadify.git"
    }
  </code></pre>
  
  <p>But all I get is the named folder containing only a <code>.bower.json</code> file, but none of the code or anything else in the GH repo.</p>
  
  <p>Running bower install directly on the cmd line gave (once I'd cleared out the bower cache):</p>
  
  <pre><code>E:/My/Path&gt;bower install https://github.com/dcneiner/Downloadify.git
  bower Downloadify#*        not-cached https://github.com/dcneiner/Downloadify.git#*
  bower Downloadify#*        resolve https://github.com/dcneiner/Downloadify.git#*
  bower Downloadify#*        checkout 0.2.1
  bower Downloadify#*        resolved https://github.com/dcneiner/Downloadify.git#0.2.1
  bower Downloadify#~0.2.1   install Downloadify#0.2.1
  </code></pre>
  
  <p>I previously did the same thing with jQuery.fileDownload which worked perfectly, so I don't <strong><em>think</em></strong> it's anything I've done to my machine?</p>
  
  <p><strong>QUESTION:</strong></p>
  
  <ul>
  <li>Have I done something wrong?</li>
  <li>Has Downloadify been set up wrong?</li>
  <li>Or is it an inexplicable mystery?</li>
  </ul>
  
  <p>In either of the first 2 cases, what is the problem and how do I fix it?</p>
  
  <p>NOTE: Currently I'm working around it by having downloaded the source code manually and having it hard-coded into my project.</p>
