I have an older version of R where I can do command completion (after
typing TAB, it will list variables that are starting with the already
typed letter. I compiled a newer version R with the default compile
options, which does not do command completion.

Since the old version can do completion, I believe that there must be
a way to configure the new version also do so. Can somebody share your
insights with me? Thank you!
