How can one link to a [[:Category:With members, but no text]] but with no action=edit produced?
Use {{fullurl}}.
Yes, but the <a>...</a> produced is many times larger than that of an internal link, a few of these and the bloat adds up.
Use {{localurl}}.
Yes, but that does not create a link.
Hack up includes/*.php.
Yes, but let's assume we are just a lowly user.
