Subject: R command prompt newline treatment

Hi Jeff - thanks. I forgot to add originally that I use putty as a
terminal for the old version of R I mentioned as well as the new, and also
I can see the same issue with the new version of R when run in xterm. I?ve
messed with some of the options putty offers and it doesnt change the new R
behavior. Also this behavior does not occur at the shell prompt, or in
other prompts, like interactive python. So while I agree that it doesnt
seem like an R issue on the surface, it only happens in R as far as I can
tell!
