Some further testing shows that for layout purposes Firefox uses \n is a  
line delimiter in their white space algorithm and \r is simply ignored.  
Internet Explorer uses \r as line delimiter and \n as _space_. Opera uses  
both, but \r\n is a single line break.

can be used for playing with this.
