Given that this function probably won't be used at all if Daiki's idea
is implemented, I think we should remove the function for now.
Daiki's approach (if I understand it correctly) of not second-guessing
what parameters gpg will need is more reliable than this approach,
even if this approach would work fine on all emacsen.
