# Splitting on a pattern: who keeps the captured delimiter, and who keeps the empties.

# Each row is one pattern and one subject, put to eight engines by
# tools/kwprobe/run.py; the cell is what that engine matched, `no`, or `-`
# when it refused the pattern. See the driver's docstring for the cells.
