a96b5f1dec Restore DOES> section in usage guide
I removed it because it was redundant with Starting Forth, but
I directly reference it in the dictionary, so well...

ecca70c7f3 Add layer of indirection to EMIT
This would allow things like temporary giving control to the *CL
line on the TRS-80. For example... A very far fetched example. Not
at all the only *raison d'etre* of the layer...

838548843e boot: apply BIN( to stray stable ABI references
With cross compiling and IMMEDIATE words, things get icky with stable
ABI references. For the same reason that EXIT, (br) and (br?) need to
stay at stable offsets, these word references will not have BIN(
properly applied at Inner core xcomp.

The solution for now is to adjust during EXECUTE, which is ugly and
inefficient, but I don't see a better solution right now.

389b23fe1a Change C<? mechanic
It's now a simple flag updated by the C< implementation. No more
routine pointer.

The goal is to avoid tons of "ok" during a LOAD operation.

816563e2e3 Stop LOADing on ABORT
This is done by adding a "C<* override" layer that is reset to 0 on
ABORT.

The problem was that when ABORT happened during a LOAD, we had a
resetted RSP and started from a clean INTERPRET, but LOAD didn't
have the opportunity to restore C<*, which caused it to continue
interpreting from the faulty BLK.

With a C<* override, we don't need to *restore* C<*, we just need to
clear the override.
