Sort of... The single "|" is the part that will get wrapped, and the 
"||" break the variosu wraps up. Look at it like this - <li 
class="first">|</li>||<li>|</li>||<li class="last">|</li>

Sort of - We have three parts, and one of them gets broken down yet into 
another two parts. Kind of like a train has three carriages, and each 
carriage can be broken into seats.

I'd always wrap the hyphen on teh first item, that way its not going to 
be there when there is no first item
