There is an alternate git history where I continued the Forth-ification of words, including "SKIP?", but that was a bad idea: because that word was written by flow control immediates, I stepped into quicksands where stability became necessary in z80c.fs and I couldn't gracefully get out of it. I'm stepping back and take this opportunity to replace the shoddy SKIP? algo with a more straightforward (?br) implementation. (br) and (?br) will always stay in boot code where it's easier manage a stable ABI.
