Pushed both patches now. Sorry Remco it took so long. To patch 1, I added a copyright line for you; even though you changed little, maybe there still is copyright together with your other patches. To patch 2, I added a period in the commit message and made the same po file change also to the new po/guix/it.po file, which previously had an invalid format string anyway.
Still for the future, IMHO editing PO files outside of Weblate is not worth the effort. Regards, Florian
