Subject: [PATCH] Add hook gpg-args to allow the user to add/remove flags

This is useful for specifying --trust-model always only for certain
GPG calls without introducing a whole bunch of new configuration options.
An example hook (which will add the ability to send encrypted email to
people to whom you have no trust relation):

  if args =~ /--encrypt/
    "--trust-model always #{args}"
  else
    args
  end
