I agree with Ludo.  These guile-colorized and guile-readline
recommendations do not appear to me the right place.  As pointed in [1],
maybe I would add a cross-reference.

The command line for Building from Git is,

    guix shell -D guix --pure

Then, the manual reads: «On Guix, extra dependencies can be added by
instead running guix shell: 

    guix shell -D guix help2man git strace --pure

» so I would avoid to overload some extra recommendations here.
Especially when such recommendations require extra configuration.
Maybe a cross-link?

The aim of this section is to explain how to build from Git and it
appears to me better to keep it straight to the point and thus to avoid
too many unrelated details (how to configure “./pre-inst-env guix repl”
for instance).  The recommendations of guile-colorized and
guile-readline are about using Guix interactively; therefore it appears
to me better to recommend and explain in the dedicated section.
