WITHIN TRUE FALSE in a new test, and * and / beside UM* and /MOD in
test_foundation.c. Executed on the golden model at both cell widths
against C on every combination of the edge values and against recorded
transcripts of the v3 binary.
WITHIN is low <= n < high with signed comparisons, which is what v3
computes; the document's circular form differed for low > high.
