[Message part 1 (text/plain, inline)]

Hi !

Thank you again for the help. I think it looks really better with the
translated reference to the info page. I feared the issues I raised
would yield unending discussions but actually with your edit it's
already pretty neat while remaining very simple. That's inspiring.

For the others interested in this thread, I also made the import of G_
from (guix i18n) explicit because it was being re-exported from (guix
ui), and while I was at it, I made the only used import from (guix ui),
that is fill-paragraph, explicit.

Hope you like this second version better : )

Alice
