There's a bug where the first char after a-lock isn't a-modded. I
have troubles figuring it out for now. It feels like deja vu. I
think I had the same problem with asm.

link: add "offset" argument to RLDICT
...
As long as our target was the first word of the "user" dict, using
target's prev to compute offset was fine, but when the target is not
the first word, this system breaks down.
This is the case when, instead of including source code in our boot
binary, we paste it in Collapse OS' prompt.
Also, adjust RC2014 recipe to include stage 3 assembling instructions
with the "paste into prompt" method.
