make it look like the other RFCs basically. and sort out the TODO

main point: without post-increment which is present in other ISAs
such as 68000 and x86 it is necessary to pre-decrement outside of
a loop. this is inappropriate in many scenarios.


> My suggested list of keywords:
> GPR, FPR, Move, Memory, LD/ST, Postincrement, Shifted-Postincrement

not Move but the others are great.
