I have now committed code using the complete: Cocoa API, but I'm not 
quite happy with it. It is severely limited - e.g. you cannot complete 
an empty string (useful for files), one-letter completions are handled 
separately (they won't complete although you get the list) and Cocoa 
has its own notion of "words" - so for example read.table is two words, 
although we'd actually like to treat it as one (I put a hack in place 
that tries to remedy that, but it's not nice ...). The good news is 
that you actually get a drop-down menu with the completion candidates 
(now it searches through all environments which may or may not be a 
good thing). I put the changes in just for users to test-drive it, but 
I think we'll end up cooking up our own solution later...

Cheers,
