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

[DaveG]

Appologies for that -- it works as expected when used on a page that's 
in the trail source. My last problem is to NOT show the trail when 
$GLOBAL["TrailSource"] is not declared.

I tried wrapping the <!--markup:... in a function, and also tried the 
MarkupToHTML, even nesting:
<!--function:ShowTrail <!--markup:<<|[[$TrailSource]]|>>-->-->

I did a quick search of the list. I think the (:trail:) markup was to 
solve a problem where there might be two lists on a page. I saw no 
further discussion, where that was developed.
