[ESS-bugs] ess-mode 5.2.1; Failure to exit with C-cC-q

[John Maindonald]

if following C-cC-q I then answer "y" to the question
"Delete all buffers associated with the R process",
I get either
(1) the message
"Current buffer has no process", or
(2) (typically but not inevitably, having exited by
typing in q() directly and restarted with M-X R)
"Matches /Users/johnmq(... [1-]"
or some variation thereof.

[This is also the 5.2.0 behaviour.  Note that in order to
use ess-5.2.1, I disabled (load 'ess-toolbar).
I had been using 5.2.0rc3].

I tried copying into my ess-5.2.0rc3 setup the 5.2.1
files ess.el and ess-inf.el.  This did not reproduce
the problem.
