[perl #60444] [PATCH] Improve junctions to store only unique eigenstates.

[Patrick R. Michaud via RT]

I'd like to get a clarification from p6l as to whether junction states
should be made unique before applying or rejecting this patch.  I'm
particularly curious about one() junctions.

Also, it seems like it would be better to make the list unique inside of
!MAKE_JUNCTION instead of duplicating this code throughout all of the
junction constructors.  This would also avoid creating yet another
private function.

Thanks!
