I think if you use  mkComplFunFromList' instead of mkComplFunFromList
that'll give completions for no text.

Maybe the problem is your use of echo? If you try in your shell,
you'll see a difference between these two:

echo a b c   def
echo "a b c   def"

One way around this might involve System.Process, :

cmd r = do
  io (readProcess "xclip" [] r)
  return ()

Or maybe the right thing happens if you just add quotes to the shell command:

cmd r = spawn $ "echo '" ++ r ++ "' | xclip"
