There are actually more than four examples that it needs to work on. And
more to the point, this is going to destroy any other numbers it finds
in the input. Phone numbers, zip codes, addresses, credit cards numbers,
timestamps, etc. will all get clobbered. It takes like 10 lines of
python to do this right; it's silly to invest a ton of effort trying to
come up with a regex solution that accidentally works.
