All the points have been addressed and I waited a period of 7 days.

Beyond this consideration, it's such a small patch, it does not break
anything for anyone, and we can always revert.

But why?

Colors used to work in Guix.  Now they are gone in Eshell / M-x shell.
It seems like a regression to me.

It's usually just 1 or 2 results then :p

I was just fixing a bug that occured in Eshell / M-x shell, without
impacting other users.

Emacs-Guix is not a drop-in replace for shell commands.  For instance,
guix search lets the user edit the results in an Eshell buffer.

Besides, Emacs-Guix is not really in sync with Guix, e.g. the lack of
channel support.

This is not changed by my patch.

We are, I'm just including further thinking into the process, that is,
Emacs Eshell and M-x shell.
