Oops, my example was obviously a little too simple.  What I am actually doing
is something like this:

#+NAME: current_data
#+BEGIN_SRC sh :dir /home/loris/remote/far/far/away/results
echo "step level time clicks"
grep statistics *.log | awk '{print $(NF-9),"\t",$(NF-6),"\t",$(NF-4),"\t",$(NF-1)}'
#+END_SRC

So Achim's suggestion of using ":results raw" might be the way to go
(once I've worked out what the sed bit is doing ...)

However, the table will ultimately be around 40000 lines long,
so from a performance point of view it would be nice not to have to pipe
the whole thing through sed, particularly as the files are on a remote
server.  Having said that though, it is not a performance-critical
application.

So maybe I'll look at Rasmus' simpler suggestion (my lisp skill are
unfortunately not quite up to the "fun" variant ...)

How complex would the elisp version of my grep and awk above be?  Just
having one code block would be a little neater from my point of view.

Thanks for all the help.

Cheers,

Loris
