bug#52093: Incorrect argument handling in "guix shell"

[Konrad Hinsen]

The following session illustrates that the -D option to "guix shell" is
erroneously applied to *two* package arguments rather than just one if
the first package argument takes the form of a file.

The file "empty-package.scm" is attached, it defines an empty package
with no inputs. The environment defined by the command below should thus
contain only "hello" and "bash", plus the run-time dependencies of
"bash". Instead, it contains the build dependencies of "hello".

$ guix shell --container -D -f empty-package.scm hello
[env]$ cat $GUIX_ENVIRONMENT/manifest
;; This file was automatically generated and is for internal use only.
;; It cannot be passed to the '--manifest' option.
;; Run 'guix package --export-manifest' if you want to export a file
;; suitable for '--manifest'.
