To be more explicit, it is because 'process-query' processes only one
query.  Which makes sense in the context of "guix package", e.g.,
"guix package --show=emacs --search=libffi" will be a bad idea, IMHO.
BUt not necessary "guix package --show=emacs --show=libffi".  I do not
know,.

There is an easy fix in 'guix/scripts/show.scm':

   (map (lambda opt (guix-package* opt)) (reverse opts))

but I am thinking if something better is possible to fix "--show=emacs
--show=libffi" too.
