RetrieveAuthPage() returns false if the current visitor doesn't
have authorization to view a given page, otherwise it returns
the page that it read.
PmWiki doesn't consider reading a non-existent page to be a "failure" --
non-existent pages are simply treated as being empty. To check for
a page's existence, use PageExists() .
