How about something like...

if (!preg_match("/^($GroupNamePattern)[\\/.]($PageTitlePattern)\$/",$pagename,
    $match))
  Redirect('Main.SearchWiki','$PageUrl?text='.urlencode($pagename));

which automatically converts an invalid pagename into a search for
any page containing that string.  This is probably a useful Cookbook
recipe.  On the other hand, in PmWiki 2 there may no longer be anything
that results in an "invalid page name", since almost every page reference
gets treated like a free link.  :-)

Excellent suggestion, although it should probably just link to 
$ScriptUrl since PHP_SELF is broken in many environments.  Added
as http://www.pmwiki.org/pmwiki2/pmwiki.php/PITS/00018.
