Blog URI: relative (/) not absolute (http). How?

My current WordPress address (URI):
http://www.website.com/wp-admin
My current Blog address (URI):
http://www.website.com
My directory structure:
http://www.website.com/archives/2004/09/slug/
The links in my sourcd code appear as:
Slug
I want it to appear without the Blog address (URI) and relative to the root directory:
Slug
I assumed leaving the Blog address (URI) general option blank would do the trick, but wordpress defaults a blank value to the WordPress address (URI) basically breaking all links. I even tried nulling the value within phpMyAdmin, but wordpress performs the same default.
Is there anywhere in the code that I can hard code/hack to force the Blog address (URI) to be relative to root and always start with a forward slash?
Thanks.
