Comma is just a separator, separating a list of items that make up
a set.  There's no special meaning attached to the comma itself.

The fullname= parameter (like most things in PmWiki) is just a list
of elements that make up a set, with a minus sign meaning "cannot be
in this set".  Thus,  "fullname=2005.*,2006.*,-*.HomePage"
would mean all of the pages in the 2005 and 2006 groups, but not
the HomePage.

It's not the comma that makes the negations, it's the minus
signs.
