Thank you. At first, I thought this round is it, but then I noticed this
line:
> +<RED>0xFF_EC_DE_5E 0b100_000 1<RESET><GREEN>0xFF_E1_DE_5E 0b100_100 2<RESET>00_000
Notice how the change from 100_000 to 200_000 breaks out the first digit
into its own token.

This line matches a non-empty digit sequence of any length, and I
thought the longest match would win. Why is that not the case here?
Frankly, I'm scratching my head over it. Any ideas?
