[ESS] launch help.start() in EWW browser

[Naresh Gurbuxani]

When running R in terminal emacs, what options are needed so that
help.start() opens EWW browser?

To find location of manuals, I run

dir(paste0(Sys.getenv("R_HOME"), "/doc/manual", collapse = "/"))

Now in emacs I can do M-x eww-open-file

Thanks,
Naresh
