title: mongoexport reading a field with a space
body: <p>I am trying to export a collection of 'contacts' from MongoDB into a CSV file.  I am using MongoExport.  My document looks as follows:</p>
  
  <pre><code>{
  "id": 1,
  "name": [
     {
          "FirstName": "joe",
          "LastName": "doe" 
     }
  ]
  "address info": [
      {
          "city": "London",
          "postcode": "N1 1AA"
      }
  ]
  }
  </code></pre>
  
  <p>The command I am using is:  <code>mongoexport --username x --password x --host x --db mydb --collection mycol --type=csv --fields name.FirstName,name.LastName,Address Info.city,Address Info.postcode --out "c:\myfile.csv"</code></p>
  
  <p>The issue I am having is getting the fields for "address info".  I tried wrapping "address info" with {} and also adding an underscore like address_info but it didn't work.  I keep getting the error:  "too many positional arugments...".  Any sugesstions?  </p>
  
  <p>Also, how can i force the command to overwrite the csv file it exists on disk already?</p>
