Hello working group,

please consider this change, even if it is very late in the
standardization process and it changes the wire format.

There is an issue with the PKESK packet: it has a fingerprint field
that is prefixed by the key version.  But, that information alone is
not sufficient to parse the fingerprint field in general, because you
cannot know the length of fingerprints of unknown key versions.
