I'm working on this.

It's a feature.  Whatever the person writes in the brackets is what
should be displayed.  If the author had wanted to have "Test.Test"
as the link text, she would've written [[Test.Test]].

I don't understand this question -- for links to pages (that don't
have ?query= or #anchor fragments), the pageurl and linkurl are
exactly the same.

It's not a big project -- I just have to figure out the appropriate
configuration variables to introduce to make it happen.

I'm not planning to do that.  The way to get that capability
would be to define a custom version of LinkPage().
