Things I never wanted to be able to do: run scanner state machines in my head. But: turns out adding %x was less work than
finding an alternative solution, once it was clear how the DFA is actually built.

It currently lives on my work-in-progress-branch for fpcres: https://github.com/martok/freepascal/commit/79873cd1c8
Proper patches will follow once things settle.
