Don,
first, you failed to tell us how you use R. There are several ways
(R.app, R from the shell, ESS, ...) and each uses a different way to
auto-complete. My wild guess is that you mean the second method
(based on your false statement about CRAN binary and libedit) and in
that case I can just repeat what has been said before ( http://
tolstoy.newcastle.edu.au/R/e2/devel/07/04/3027.html ) - please read
the NEWS.
Cheers,
Simon
