Oh I see that darcs-2.8.5 still works in a hashed repository. I was not 
aware of that.

Btw. are the exponential time merge problems solvable within the darcs-2 
semantics or does it need a darcs-3? And what about new modification types 
like indentation changes - would this require darcs-3 semantics?

This would be great! I hope that the code.haskell.org maintainers can wait 
for this time.
