Not returning required flag for trailing CR LF

[toptensoftware]

If a string ends with '\r\n' the final returned line break position doesn't have the 'required' flag set.

This line should include a check and return appropriately:

linebreak/src/linebreaker.js

Line 194 in 9096a22

return new Break(this.string.length);

eg: perhaps this:

var required = (this.curClass === BK) || ((this.curClass === CR) && (this.nextClass !== LF));
return new Break(this.string.length, required)
