Yes David, it's this commit indeed (Traduction #9173 proposée par Sylvain Loignon).
Here's what I did to "convert" it to fr (one it was committed in fr_ca):
- Wait til the lang pack was updated on download.moodle.org
- Download the fr_ca lang pack
- Locate the appropriate php file
- Feed AMOS with it in the fr language
- Commit it
A bit tricky, so I would support the feature request that would enable to do it inside AMOS
