The traditional way to adapt wikitrails has been to create a custom trailstop
function, as in:

    include_once('scripts/trails.php');

    function CustomTrailStop($link) {
      global $pagename;
      $t = ReadTrail($link);
      // ... rest of code copied from MakeTrailStop here, with modifications
      return "whatever you want the trailstop to output";
    }

    $DoubleBrackets["/<<\\|($TrailLinkPattern)\\|>>/e"] =
      'CustomTrailStop("$1")';

Calling this variable $WikiTrailFmt is misleading, since it doesn't
get processed by FmtPageName and other $-variables aren't substituted.
We could name it something else (or I suppose we could make it into
a standard FmtPageName-processed string).  Still, I think I prefer
to just have customizations done as custom functions for now...
