It's not there, because some of the shells that run R supply it. I don't 
use one, but I think a couple of the popular ones are ESS and the Mac OS 

It would be a nice addition to the Windows GUI, but I don't know anyone 
who is working on it.  I don't think it would be a welcome change to the 
console versions; some of them use readline's filename completion which 
would almost certainly be broken by this.  Others need to run under ESS.
