PmWiki doesn't run the markup engine on each iteration --
it concatenates all of the iterations together into
a single markup string, and then runs the markup engine on
the concatenated result.  Thus, we can't know which 
iterations generate output.

The problem becomes even worse if we do "inline pagelists",
where the markup is inserted directly into the surrounding
page as opposed to being converted into HTML inside of the
(:pagelist:) command itself [1].  In that case we *definitely*
don't know the result of any conditionals within iterations 
before the overall page has been processed.
