Wiki Markdown Links are not rendered correctly with double bracket syntax

Using double square brackets [[some-text]] in wiki's prevents all text on the same line as the link from being rendered.

Original Description

On GitLab wiki page, in Markdown format, I want simply to place link to article "foo" and that link should show up as "foo".

There is no damn reasonable way in GitLab to do this most obvious task.

Using double-square-brackets has a bug and deletes all text in same line.

Only way that works is to TWICE type name of the article "foo" but that is stupid and can lead to mistakes.

It worked on GitHub.

Please make the double-square-bracked links work without the bug, [[foo]] should become link "foo" to article "foo".

Bonus task: Also support [[/foo]] for nicer format, and [[./foo]] for relative links (show links title same, as "/foo" and "./foo" to inform user where he will go)
