Hi,

attached you find a patch allowing the user to add/remove flags before running
GPG.  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

Please merge this patch for the next release

Best regards,
Michael
