Thank you, Bruno.  So the syntax is different in GPG and PGP.
Wouldn't it be better to have a separate encrypt-pgp-process-buffer
function?  They may be similar (and I will abstract what I can), but I
don't want to add extra parameters to the GPG function for PGP
functionality.

I only use GPG so I'm looking for opinions...
