title: When using Python docx how to enable spelling in output document?
body: <p>I'm using the Python docx library to generate an document, that I would like to be able to open and find spelling errors in.  But when I open the document none of the spelling errors flag (little red underlines) or are identified if I run a spell check.  If I edit a line or copy, cut and paste the content back into word the spelling functionality works as expected.  </p>
  
  <p>Is there some way to get the output document to display/recognize spelling errors in the output document automatically?  I've played around with the "no_proof" flag but that doesn't seem to help.  (Using 64 bit Python 3.4, docx 8.6 on a Windows box, Opening output in Word 2013)</p>
  
  <p>Thanks for any ideas!</p>
  
  <p>Code to reproduce:</p>
  
  <pre><code>from docx import Document
  document = Document()
  paragraph = document.add_paragraph('This has a spellling errror')
  document.save(r'SpellingTester.docx')
  </code></pre>
  
  <p>Output in Word :
