Cool, I didn't know that worked.  In that case it makes sense to
immitate pre-v5 format.  Will change this in the re-roll.

Just a heads up about my progress, I'm currently trying out your
suggestions about storing the directories as tree-format when reading
and storing the dummy entries in the index.  I'll make some experiments
to see if the change is worth it, and will then send a re-roll, probably
in a couple of weeks.
