[ESS] Sent lines (through C-c C-n) are not written in the history

[Sebastien Vauban]

Hello,

If I send lines from my R buffer to the iESS process with commands such as `C-c
C-c' or `C-c C-n', these are NOT copied to the history -- while I'd find that
very useful: I can update some commands and test them before editing the code.

Is this intentional?

Is this customizable?

Best regards,
  Seb
