All of them do.

It must have been the crack talking, though; I think something went weird
with my checkout.  I'm positive I re-checked out because I'm building out
of a local packaging setup, which deletes and re-checks out each time. 
However, I just ran it again and it worked alright.  Sorry about the
confusion.  Looks like that patch fixes it for me.  :)
