I'm not sure -- someone can check -- but since TDobes wrote that, I think the 
output of theme_get_style was reversed. I believe this is the case since at one 
point I'd hacked my template.php on a site to do just that because modules using 
theme_add_style screwed things up. After an updated, I had to remove that hack; 
turned out the module was still using theme_add_style.
