Hyphenator.js or html5 word break

Tom Shand of the http://www.theinternet.co.nz sent me an email earlier today to show me Hyphenator.js, but I'm wondering why the demo didn't include the example below......

This is a very long sentance and right at the end of it there seems to be a breakintheword.

This is a very long sentence and right at the end of it there seems to be a breakintheword.

Below I'm using the wbr tag, but I'd like to know if it's possible to do this and have a - Hyphen added when it decides to move to the next line.

Anyone?
