Trying to parse the W3C sample, it fails in 3.3 (while it passes on 2.7). (last example)

   Content-Type: multipart/form-data; boundary=AaB03x

   Content-Disposition: form-data; name="submit-name"

   Content-Disposition: form-data; name="files"
   Content-Type: multipart/mixed; boundary=BbC04y

   Content-Disposition: file; filename="file1.txt"
   Content-Type: text/plain

   ... contents of file1.txt ...
   Content-Disposition: file; filename="file2.gif"
   Content-Type: image/gif
   Content-Transfer-Encoding: binary

   ...contents of file2.gif...

(broken) test attached.

At first glance it seems related to rev d864328a74e4 , issue 4953

The check on self.bytes_read >= self.length returns True because length == -1.

This seems to fix it.
