I am not sure, I understand.  In the 'naked' R console, incomplete input
seems to produce a '+' prompt, while complete input seems to produce an
empty prompt.

As in

| > Sys.sleep(10
| +


| > Sys.sleep(10)

So, there seems to be a distinction.  As in my original example, the
number of '+'es differs.  Can't ess count them for me?
