I've submitted a -01 with these changes:

 - better documented the motivation for the new Accept headers (improved
   interop without having to modify HTTP implementations, just
   applications)

 - removed special values of Accept-Auth

 - added Accept-Redirect and Accept-Redirect-Auth headers

 - for the Redirect auth scheme, limit preservation of the Authorization
   header and add an Authorization-Request header that is always
   preserved

 - expanded discussion of redirect-based auth protocols

 - improved Security and IANA Considerations text

 - misc changes

The new Accept headers and the new auth scheme are now much more
separable.  This I-D could now be split into two I-Ds.
