Well, if someone is going to customize $PageEditFmt, they may or may 
not want to include the template functionality, but I see your point.

Here are some more ideas.

Often one wants to "add a page like this" to a list.  It's a two step 
processes; adding to the list, and adding the page.

So, on the list page, you customize $LinkPageCreateFmt like this:

$LinkPageCreateFmt = "<a class='createlinktext' 
href='\$PageUrl?action=edit&template=ItemTemplate'>\$LinkText</a>";

(where I have omitted the '?' for clarity).

Then you just add the new pagename to the list, like
	* TheNewItem
and save the page.  Then when you click on the link, it automatically 
loads the template into the text field, via something like

   if (isset($_GET['template']))
     $new['text'] = GetTemplatePage($_GET['template']);

in HandleEdit(), just before calling the EditFunctions, where 
GetTemplatePage is basically

function GetTemplatePage($pagename) {
   Lock(1);
   $p = RetrieveAuthPage($pagename,'read');
   if (!$p) Abort("?cannot source $pagename");
   return $p['text'];
}

Another approach is to customize $DefaultPage or $PageNotFound for the 
list page to be something like (:include template:).  Then the edit 
link would work automatically without needing to add arguments to ?action.

By the way, how do you customize a variable for one page?  I guess you 
could do it in the GroupHeader using conditional markup based on the 
PageUrl, or perhaps there is a directive that sets a variable?
