Parker Coates 13033d87a1 GH-19: Respect the HIST_FIND_NO_DUPS option. 
This is the best way I've found to remove duplicate entries while
keeping the most recent occurence, but I'm not a ZSH expert. There may
be a more efficient way.

Parker Coates fd31074470 Use array reversal instead of array sorting. 
There's no need to do a full numerical sort here, since we know the
keys will be in reverse numerical order, because (R) searches in last-
to-first order. Not a big deal, but this is just simpler and
presumably more efficient.

Also cleaned up a rather confusing comment about (on) being used to
remove duplicates, which it definitely doesn't.
