Uh, weird.  I do encounter it like this:

--8<---------------cut here---------------start------------->8---
$  guix time-machine --commit=6b588da368c77cde82ea2f22ca315116228777ad -- shell 
--export-manifest texlive-base rubber
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.
(concatenate-manifests)
--8<---------------cut here---------------end--------------->8---

Yes, done.  That’ll need some investigation…

Thanks for the heads-up!
