I think there is a misunderstanding because we are not talking about
Emacs but about "terminal emulator" (and Emacs happens to be one).
And we are talking how to enable OSC and colouring in the terminal emulator.

It has been done using INSIDE_EMACS because most of us use Emacs as
terminal emulator (eshell or shell-mode).
But IMHO, it is not the issue. The issue is:
 - how to turn on/off the OSC in *any* terminal emulator (supporting
or not OSC).
 - how to enable/disable colouring in any terminal emulator.

Here, it is the same. The question is how to disable the behaviour
using whatever terminal emulator.


And instead of multiplying* the environment variables, we should add a
file in ~/.config/guix/config.scm to set the user preference. WDYT?
