Right, this is simpler, but I still need to:

- Clear the <input type="file"> selection I've replaced with processed
  files, so they don't get submitted as well.
- Allocate the XMLHttpRequest
- Handle the response
- Process any eventual redirects.

This is all fine when you want to do AJAX, but unless HTML5 drops
regular non-AJAX <form> submission, I don't understand why we would
mandate that processed File submission be done only using AJAX.
