Passing a nonexistent file as --expose leads =E2=80=98guix environment=E2=
=80=99 to
silently fail:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc guile --expose=3Ddoes-not-exist --container
guix environment: warning: ambiguous package specification `guile'
guix environment: warning: choosing guile-2.0.11 from gnu/packages/guile.sc=
m:125:2
$ echo $?
1
--8<---------------cut here---------------end--------------->8---

It would be nice to print an error message.
