here's my second question: 

given a list like this
'(
"matt@mdke.org  Matthew East"
"matt.price@utoronto.ca Matt Price
"matthias.doerries@gersulp.u-strasbg.fr Matthias Dörries"
"matthewreedy@yahoo.com matthewreedy"
)

how to i tell emacs i want to use the list elements as choices for
tab-completion in an interactive function?  so if i have a function like
this:


(defun query-python-addressbook (name)
  (interactive "s To:" )
  (setq cmd-name "python /home/matt/evo-query.py")
  ;; imagine sh-output generates a list -- see my last email in this
thread
  (setq sh-output (shell-command-to-string (concat cmd-name " " name)))

  )
can I write another couple of lines that presents the items in the list
as choices to the user, who then picks one?  that'd be really great.  

that's about as far as i can get so far.  thanks again!

matt
