This feature allows to fetch keyblock by keyblock from an LDAP server.
This way tools can process and maybe filter each keyblock in a more
flexible way.  Here is an example where two keyblocks for one mail
address are returned:

  $ gpg-connect-agent --dirmngr
  > ks_get --ldap --first  <foo@example.org>
  [... First keyblock is returned ]
  OK
  > ks_get --next
  [ ... Next keyblock is returned ]
  OK
  > ks_get --next
  ERR 167772218 No data <Dirmngr>
