The title states it all. Bug is present in 1.2 and 1.3 branches. Illustration:

$ weboob-config --quiet update 
=== [  0%] Getting http://updates.weboob.org/1.2/main/
=== [100%] All modules are up-to-date.

$ ~/.local/venvs/weboob/bin/weboob-config update --quiet
=== [  0%] Getting https://updates.weboob.org/1.3/main/
=== [100%] All modules are up-to-date.

Particularly annoying for me because I want to update modules through a cron job and would like to receive no notifications when everything runs smooth.
