Hi Bram,

You are right I was also confused by this a couple of month ago.

Can you create something similar to the figure on the left and something 
that look like
the joints figure in the wiki so we can display the right one.

You can add an hinge or a ball between the block and the cylinder but 
you will need an extra body.

Block body -> Hinge Joint -> Extra Body -> Slider Joint -> Block body

I created a new joint which I call "Rotoide prismatic"  but the rotation 
axis is perpendical to the axis of the  slider.

I should be able to create a patch to submit in the next following days.
