The bug in jqueryMsg that required this is now fixed. Depends on
I56d8f7ec03a70f5c2360d9c5099496ecb2f668ad and
Icc360724c75755a6ffc31792d8439cba142642ae in MediaWiki core.
Changes to messages were done with search-and-replace:
<a $2> ---> [[{{ns:template}}:$1|
</a> ---> ]]
{{GENDER:$3 ---> {{GENDER:$2
