names of languages (gcr) and (hyw) in French
Patch created: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/cldr/+/627812 waiting for review.
You ask me to review it in GerritWikimedia, I've replied to the notification I received by mail, but GerritWikimedia fails to login me: I have an account, it was created, I have tried resetting the password, it worked, but then the logon screen rejects the logon/password (visibly it has a bug if it does not accept the underscore in my user name, even if it created the account with it!)
Anyway I can reply here that your patch (for LanguageFr.php in Mediawiki's localisation files) looks good for me (from the diff displayed).
You may include a link in Gerrit showing this talk thread with my review here, if you did not receive my reply by mail after the notification I received, or you can copy-paste the previous paragraph.
The patch was reviewed and submitted a few minutes ago. Should go live on Wikipedias & Co next week.
