Oops.  The version of pmwiki-2.1.beta36 that I just released also
added the (:if exists:) markup, albeit for a single non-wildcarded

I looked through the PublishPDF's source for its definition of
(:if exists:) but couldn't find it.  

If PublishPDF defines $Conditions['exists'] forcefully (i.e., not
through an SDV() call) then it will override pmwiki-2.1.beta36's
definition without loss of functionality.  If PublishPDF uses SDV,
then I probably need to fix the distribution.

The long-term goal of the builtin (:if exists ...:) will be to
handle both wildcards *and* multiple page existence tests.
If it's important that this get resolved quickly, I'll see
about writing it for the next release.
