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))"
