Subject: [openpgp] Proposed Patch to RFC4880bis to reserve two public key numbers

From: Derek Atkins <[email-masked]>

Hi,

The attached patch to RFC4880bis reserves two public-key parameters.
They are specified as "reserved" and I've added text to 13.8 as well
documenting that they are underspecified.

Note that these are NOT "MTI" algorithms in any way, shape, or form!

Thanks,

-derek
