Thanks Jeff, that gives me the proper starting points for writing
the enhancement. I'm glad the bug is marked with Low priority and
Minor severity, that give me the time to grasp all the mechanisms 
involved :)

I assigned the bug to myself, I hope that is the proper way to use
bugzilla (as this is my first time to write code to solve an 
already listed bug).

Cheers,
