I was thinking about exactly this item when I woke up this morning --
with the new wildcard handler in place I'm thinking we can have
an (:if exists <pagename>:) conditional that also understands
(:if exists Group.SomePage:) -- true if Group.SomePage exists
(:if exists Group.* :) -- true if any pages in Group
The first test is very fast, because it can look immediately for
a known pagename. The wildcard version will often be a fair bit
slower because it requires scanning all of the page directories...
but at least it would work. Besides, this would normally be done
only for missing pages, which is fairly rare anyway.
