I'm thinking that something like

#+PROPERTY: header-args:R :session "*R*" :exports none

should work.  I've checked that the property interface returns the data
as expected, but I haven't implemented anything yet.  It does not seem
to be an overly difficult endeavour, however.

General settings for all languages should be effected by

#+PROPERTY: header-args :results value :exports none

and there'd be a list of header arguments (or specific values) that are
either ignored or warned about when not associated with a particular
language.

BTW, I think the current property syntax for header arguments should be
deprecated since it is the only place where the leading ":" is missing
for those.

Comments, thoughts?
