It isn't R! This is a function of readline and the terminal, not of R
which has not yet seen the line.
What is likely is that your R install (how did you install it?) is built
against a readline clone (I believe there is one from NetBSD? in MacOS
10.4) rather than GNU readline, and the fix is likely to be to install GNU
readline and then rebuild R from the sources.
