(setq ac-auto-start nil) causes ESS auto-complete to crash

[sfischme]

1. Load up R file
2. start up R interpreter session in other buffer
3. try auto-complete (=> should work)
4. set ac-auto-start to nil
5. try auto-complete (=> should fail)

A colleague found this likely source of the problem in ess-r-d.el:

(if (< (length ac-prefix) ac-auto-start)

Thanks for this. I cannot reproduce, but your diagnostic seems right so I added a check for non-nill value. I would appreciate if you could check if it works now.

Ah ok, I can reproduce. Subprocess should have been connected as you pointed in your instructions. No need for a check. I can see that the fix works as expected. Thanks again.
