title: Eco Error Message: Unexpected 'INDENT' in Windows
body: <p>I'm currently using spinejs and eco template system in rails project. It's work perfectly on my Mac, however there is a strange indent error when I deploy it on Windows. And the code is:</p>
  
  <pre><code>&lt;div class="contacts"&gt;
      &lt;% for contact_record in @unchecked_contact_records : %&gt;
          &lt;%= contact_record %&gt;&lt;br&gt;
      &lt;% end %&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And the error message is:</p>
  
  <pre><code>ExecJS::ProgramError in Admin#dashboard
  
  Showing C:/Users/rayshih.mama-PC/workspace/showwin_ror_1_5/app/views/layouts/application.html.erb where line #6 raised:
  
  Error: Parse error on line 2: Unexpected 'INDENT'
    (in C:/Users/rayshih.mama-PC/workspace/showwin_ror_1_5/app/assets/javascripts/admin/views/dashboard/contacts.jst.eco)
  
  Extracted source (around line #6):
  
  3: &lt;head&gt;
  4:   &lt;title&gt;Show Win Printing Service&lt;/title&gt;
  5:   &lt;%= stylesheet_link_tag    "application" %&gt;
  6:   &lt;%= javascript_include_tag "application" %&gt;
  7:   &lt;%= csrf_meta_tags %&gt;
  8: &lt;/head&gt;
  9: &lt;body&gt;
  </code></pre>
  
  <p>I thought this is a problem only on block statement, but by this experiment:</p>
  
  <pre><code>&lt;div class="contacts"&gt;
      &lt;% if true: %&gt;
          &lt;%= "hello world" %&gt;&lt;br&gt;
      &lt;% end %&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>In this experiment, there is no error. So this is not a block statement bug. Seems like it only happen on for loop statement, but why?</p>
