The older (commit bed47b437d8cde7a98bafdb07996e248b40f70e6e) version of 
org-babel-comint-with-output used comint-prompt-regexp and works fine.

I don't really follow how `org-babel-comint-prompt-separator` gets set to 
something useful in the current version. 

Reverting org-babel-comint-with-output to that older commit (and eval-ing the 
defun for org-babel-R-evaluate-session) seems to fix this case for those who 
need `:results output` in R src blocks till this gets sorted out.

HTH,

Chuck
