Dear,

This patch adds the feature:

  guix package --show=emacs --show=hello

and therefore, it allows to pipe:

 guix graph emacs --path libffi | xargs guix show


Note that:

 1. "guix package" processes from right to left.
 2. "guix show" processes from left to right.

It is how "guix packages" is implemented.  However, it appears more natural to
display in order; that's why "guix show" reverses the order.

 3. Because dealing with multiple different queries does not seems "keep it
 simple", "guix package" starts with the last query (the most of left) and
 then processes all the queries corresponding to this one.


For example,

a) guix package --show=emacs --search=hello --show=libffi
will show the packages 'emacs' and 'libffi', skipping 'search'.

b) guix package --show=emacs  --show=libffi --search=hello
will search the package 'hello', skipping 'show'.

It is already how '--search' works and has been extended to '--show'.  Does it
need to be documented in the manua?



All the best,
simon
