[ESS] Documentation of thing at point

[Sebastien Vauban]

Hello,

I would like to be able to look up documentation of "thing at point"
with `info-lookup-symbol' (`C-h S' in Emacs Lisp buffers, and in all
modes for me...).

However, in my case, it does not return anything...
See http://screencast.com/t/sU27gqjr45.

Am I missing something in my configuration, so that the R documentation
can be integrated within a generic way to access it (other than `C-c
C-v' which is only usable in ESS buffers)?

Best regards,
  Seb
