It keeps prepending the domain name so you get http://www.google-com.topcat.switchinc.org/http://www.google-com.topcat.switchinc.org/<http://www.google-com.topcat.switchinc.org/http:/www.google-com.topcat.switchinc.org/>/ after the second pass, after the third pass you get the full domain three times and so on.

If you know how many you're dealing with, but don't want it to pass 
through quite as many rules, you can use a power of twos trick:

1. Have a rule that replaces 4 dashes
2. Have a rule that replaces 2 dashes
3. Have a rule that replaces 1 dash

it'll then handle between 0 and 7 dashes.

At 6, this might not be worth it ... when you start getting above a dozen 
(which hopefully you'll never have to deal with), it might be.
