[Dave Abrahams]

New submission from Dave Abrahams:

compare the output of

$ python -c "open('/tmp/tst','w').write(100*'x\n');import re;print len(re.split('\n(?=x)', open('/tmp/tst').read()))"
100

with

$ python -c "open('/tmp/tst','w').write(100*'x\n');import re;print len(re.split('\n(?=x)', open('/tmp/tst').read(), re.MULTILINE))"
