Do you have an illustrative pair of programs that did not work before, that works now?

Yes, they are anchored in the tests and have been pulled from https://corewar-docs.readthedocs.io/en/latest/redcode/addressing_modes/#a-post-increment-indirect and https://vyznev.net/corewar/guide.html#start_modes and been slightly modified. Theoretically the scanner should be broken without this

LGTM

Theoretically those should look different between mainline and this branch:

DAT #0, #4
MOV 0, >-1
jmp 0

[0815sailsman]

sure

After further discussion and further checking the source code attached in the '94 standard, it seems that https://vyznev.net/corewar/guide.html#start_modes contains incorrect information and the original implementation was correct after all.
Changing this to simply add the until now missing tests

[0815sailsman]

sure
