I think I took this from some old posting of Martin somewhere. I see --no-restore-history does not even avoid the "Cannot read history file" warning message that IS confusing for newbies (I see my students thinking something went wrong starting R).

So, --no-save only?

Not that I kept much up to date on this issue, but that's the first time I read about the "RRR" indentation style. Can you elaborate a bit about it? How does it differ from "C++"? Also, I figure it is different from "DEFAULT"?
