Change Details

According to the documentation, [iw_prefix](https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:interwiki_table#iw_prefix) is `varbinary(32)`, while [iwl_prefix](https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:iwlinks_table#iwl_prefix) is only `varbinary(20)`. This may result in truncated interwiki prefixes in the `iwlinks` table and bugs such as [this query](https://wiki.archlinux.org/api.php?action=query&prop=iwlinks&titles=Forum%20etiquette) where the prefix should be `archlinux-service-agreements`, but instead it is truncated to `archlinux-service-ag`.
