Thanks for your reply Eli, and thanks for your work on Emacs.

The reason I thought it was an Emacs problem was that the problem
happens consistently in Emacs 26.3 but not in Emacs 25.3.1. But I
don't have a lot of knowledge about Emacs, so there could be something
I'm overlooking.

I wouldn't expect that you could reproduce it on a system without R,
because it only happens (as far as I know) if C-c C-c is pressed with
the right Control key in an R console buffer. It doesn't happen if I
press C-c C-c in a different buffer.
