4 should append current word to the memory

[pragmatic]

I'm able to do the pieces I was requesting about mirroring without duplicating the last letter which is great.

rules:
:
M r [ 6

>hashcat-cli64.exe test.txt -r test.rule --stdout
123456789
12345678987654321
race
racecar
madami
madamimadam
satanoscillatemy
satanoscillatemymetallicsonatas

Thanks for that!
