Or we can just document that ESS defaults are used for sessions and ask
users to customize inferior-ess-R-program if they need something
non-standard for sessions.

The problem with `inferior-ess-R-program' is that it must be executable
name, and cannot be command with arguments, as in our default value of
org-babel-R-command: "R --slave --no-save". In the absense of people who
are actually making use of the proposed feature, I see no reasons to
complicate the code.
