[colorforth] Question regarding if

Sorry, this is not equivalent. For purposes of equivalency:

: eq or if dup or drop ; then - -1 ? drop ;

Inefficient, yes. That is why one should think of 'if' as jump to then if
the result was zero. 'less' should be thought of having a result of true
(not zero) if the second item was less than the top. And '-' should be
changed so it effects the flags properly. This will make colorForth
logically consistent.
