How would I go about adding a character between each of the categories in the Categories Tabs Menu? I'm guessing its nothing under NavCatTabs in the stylesheet, so would have to be in tpl_modules_categories_tabs.php...

Instead of it listing them as:
Category 1 Category 2 Category 3
I would want it as
Category 1 | Category 2 | Category 3


I don't want the spaces and the " | " separators to be linked though...
