Hello Guix!

Here’s a gift brought from the R-B Summit in Marrakesh!  :-)
These changes allow ‘guix challenge’ to directly show the list
of changed files, or to invoke ‘diffoscope’ on the differing
store items.  The new ‘--diff’ option allows users to choose
the diff mode.

The default now looks like this:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix challenge guile --substitute-urls="https://bayfront.guix.info https://ci.guix.gnu.org"
/gnu/store/1mkkv2caiqbdbbd256c4dirfi4kwsacv-guile-2.2.6 contents differ:
  no local build for '/gnu/store/1mkkv2caiqbdbbd256c4dirfi4kwsacv-guile-2.2.6'
  https://bayfront.guix.info/nar/lzip/1mkkv2caiqbdbbd256c4dirfi4kwsacv-guile-2.2.6: 1pzzanrfpjmmm6qbgw03qnjmj9zvd4af8sqk44y3m3k36l0dxgwq
  https://ci.guix.gnu.org/nar/lzip/1mkkv2caiqbdbbd256c4dirfi4kwsacv-guile-2.2.6: 1qhxajxihs3gm4ny61hq9zjnssp8azzsxflk9wq4l8g2l3zicp52
  differing files:
    /lib/guile/2.2/ccache/srfi/srfi-27.go
    /lib/guile/2.2/ccache/srfi/srfi-19.go
    /lib/guile/2.2/ccache/srfi/srfi-18.go
    /lib/guile/2.2/ccache/ice-9/vlist.go
    /lib/guile/2.2/ccache/ice-9/suspendable-ports.go

1 store items were analyzed:
  - 0 (0.0%) were identical
  - 1 (100.0%) differed
  - 0 (0.0%) were inconclusive
--8<---------------cut here---------------end--------------->8---
