Hello,

Currently, if you have an authorized manifest available and want to run 
some command (for example htop) provided by the manifest, you need to

--8<---------------cut here---------------start------------->8---

$ guix shell
$ htop

--8<---------------cut here---------------end--------------->8---
as supplying a command for guix shell makes it to not look for 
manifests, and instead simply create a empty environment.

--8<---------------cut here---------------start------------->8---

$ guix shell -- htop
guix shell: warning: no packages specified; creating an empty 
environment
guix shell: error: htop: command not found

--8<---------------cut here---------------end--------------->8---

Which doesn't seems a desirable behavior to me. Could we fix it?

Thanks in advance,
Luis

This is the documented behavior: =E2=80=98manifest.scm=E2=80=99 and =E2=80=
=98guix.scm=E2=80=99 are read
only for interactive use, meaning without =E2=80=98--=E2=80=99:

  https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-shell.html

The rationale for it is that non-interactive uses of =E2=80=98guix shell=E2=
=80=99 would
always be self-contained.

This was arguably a very conservative choice but I=E2=80=99m not sure we can
change it at this stage.  Thoughts?
