Even worse, you can't do this when the data comes from a pipe.  
We already use several hash contexts to work around PGP bugs.  I am
not in favor of setting up even more.  If the message is correctly
encoded, we can hash the data using more than one algorithms, it is
just a matter of enabling the algorithms for the hash context and
doing a md_copy right before hashing the signature specific part.
