Sorry, I missed the initial property line where you set the ":session"
header argument.

When I set the ":session" header argument, I get the original buggy
behavior that you report.

It looks like the reason for this, is that the substrings like "tr>"
match `comint-prompt-regexp', and so get stripped out by
`org-babel-comint-with-output'.

I think a more reliable implementation would be to avoid
`org-babel-comint-with-output', and take the approach used in the
":results value" case, which reads the output from a temp file instead
of directly from the shell.

Actually, that's the approach I use in my ob-session-async package [0],
which re-implements ob-R sessions to allow async evaluation. It doesn't
suffer from the bug you are reporting. I'll plan to extract that
implementation and submit it as a patch here.

Long term, I am intending to contribute the full functionality in
ob-session-async here, but that's still a ways off.
