Virgil Dupras 2d17b4e8ec Make string length-prefixed instead of null-terminated
I'm not sure why I chose null-terminated initially. Probably because
the z80asm version had null-terminated strings.

Length-prefixes strings are the traditional form of strings in Forth
and it's a bit easier to work with them with traditional forth words
when they're under this form.

( strings being sent to parse routines are always null
terminated )

DUP 1+ C@ 39 = OVER 3 + C@ 39 = AND ( a f )
NOT IF 0 EXIT THEN ( a 0 )
( surrounded by apos, good, return )
2+ C@ 1 ( n 1 )
