Only way to have a unified markdown syntax is to enforce the wanted
syntax by linting the files. Don't rely on the many markdown syntaxes,
be consistent.
Split-gpg V1 allowed for querying public keys, but as split-gpg2 is
running as an agent, public keys are not queried. Allowing connection to
the server to query only public parts of the key exposes the server more
than needed to the client.
All clients now have to hold the public key they need locally in order
to do GPG operations.
