Then why do it?  Why not just do  echo false ?

...but the above pattern *isn't* always returning every page,
it's returning only those page names that aren't in the PmWiki
or Site groups.  In particular:

    echo (boolean)MatchPageNames('Forum.Page1', '-PmWiki.*,-Site.*');  # true
    echo (boolean)MatchPageNames('Site.Site',   '-PmWiki.*,-Site.*');  # false

I think I need to see a much larger example of what you're trying
to do.  The MatchPageNames() function says "return a list of all
of the pagenames in the first argument that match the pattern given
by the second".  If you want to restrict that to a certain inclusive
set, then just put the inclusive set there.
