2e9e7047bf Make INTERPRET break on ASCII EOT
This should allow me to simplify LOAD's exit mechanism on block
end.

33d37d4ce9 WORD: don't overwrite RAM on words over 31 chars
This allows me to reclaim some RAM I hadn't even noticed I
needlessly monopolise.

3d908cef3a Move all parsing words to Inner core
This allows us to get rid of the (parse*) indirection.

446a58006d Remove one of the 2 indirection layers for EMIT
2 was overkill

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...

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.

af39b37dd1 Replace the "> " prompt with the more traditional "ok" one
This is more than cosmetic, it's also highly usable. The presence
or absence of the "ok" message allows us to know whether the command
aborted. Previously, the "> " prompt appeared when the system expected
a prompt in the INTERPRET context, whether the previous command aborted
or not.

Also, this allows us to get rid of that ugly FLAGS global variable.

target!
