Thanks. I'll need to find some time to review the changes. You may wish to add 
a PITS entry for this feature request, to see if there is some interest and 
consensus among the community about implementing it. If not, you can always 
release it as a recipe.

Just letting you know that you can easily override the default trails.php 
script like this :
* move your modified file from scripts/ to cookbook/
* add to config.php :
  $EnableWikiTrails = 0;

This way, your wiki will use your own functions instead of the default ones, 
and will not break on upgrades.

I disagree. Guillemets (angle quotes, ») are indicators for quoted 
speech. We should use arrows (→) if we want to indicate arrows. :-) 

Moreover, right arrows will only work in case of ^|Trail|^ and not with 
<|Trail|> or <<|Trail|>>. The vertical bar works in all cases, and I feel the 
first case is the least common one.

At any rate, users can add to config.php 
  $TrailPathSep = ' &raquo; '; 
or something different to override the default vertical bar.
