Thanks a lot!  I looked into tabulated-list-mode and EWOC, and it seems
that EWOC is the way to go for me.

I have a few questions, though.  One thing I'd like to have is /sorting/
of the `things' in my ewoc based on different criteria.  Do I get it
correctly that I'll have to `ewoc-create' it from scratch?  DO I get it
correctly that I can just safely (setq my-ewoc (ewoc-create ...)),
knowing that the old one will be GC'ed automatically?

Also, I'd like to color various entries in my ewoc, using different
faces.  Do I get it correctly that I should assign them faces right
after `insert'ing them in my pretty-printing function?
