[pmwiki-users] Wiki trail in template header and footer

[DaveG]

Spoke too soon. What we end up with is a trail with no prev/next links. 
I get the text where I want it, but I suspect the trails.php isn't able 
to function from inside a template, as trail.php looks for the name of 
the template in the trail base list, can't find it, and thus shows no 
prev/next links.
