This is a legit issue. The demo demonstrates the problem pretty well.

The author of this issue used a very special maze-like map with thin walls. The 
hedgehog ropes to a perfectly vertical wall, falls down until there is an 
opening in the wall an shoots the rope to the left. The trick is, the rope gets 
attached on the wall right to it, after the hedgehog has fallen below the 
opening in the first fall. And this way the rope goes actually through the 
first wall.

Odd.

Yeah, was chatting about it w/ unc0rr in context of rope speed changes.  
Probably would require more looping and collision tests in the rope code, which 
is a bit of a shame.
Luckily super-thin walls is pretty rare, 'cause it probably screws w/ hedgewars 
collision elsewhere too.  Drawing for example, unc0rr sets a minimum size of 
6px.

It might be that this is a legit bug, but whether we want hedgewars to 
consistently and reliably support super-thin walls...
