A recent change to MediaWiki software seems to have broken templates
everywhere. The syntax
used to work on a template to generate a link to a page in the same
namespace, typically used on templates related to move (rename) discussions.
However this has stopped working as of last month, causing lots of
[[::ABC|ABC]] to be displayed in plain-text everywhere when this syntax is
used in the main namespace.
We figured for now at yue.wp that
(notice the deletion of the colon at the beginning) works and would like to
know if this is the recommended solution. This doesn't seem to have been
picked up by Linter.
