[ESS] completion using ess-remote

[Mathieu Basille]

Dear François and Rodney,

For me, the problem is not with ESS-remote, but with the use of screen. 
Here is what I can reproduce:

- On a Debian Squeeze laptop, using Emacs 23.2+1-7 and ESS 5.11-1 (and R 
2.13.2-1~squeezecran.0 for what is worth);

- If I connect to a remote server running Debian Wheezy, and R 2.13.2-1 
(and Emacs 23.3+1-1.1 and ESS 5.14-1 for what is worth);

- With a simplified .emacs as:

(require 'ess-site)

- If I'm not using screen but a direct R process within the terminal, I 
have access to completion.

- If I use a screen session, I cannot anymore, with the same (I think) 
messages as you:

 > as.character(getRversion() >= "2.7.0")
[1] "TRUE"
 > rcompgen:::.assignLinebuffer('bar')
Error in loadNamespace(name) : there is no package called 'rcompgen'
 > rcompgen:::.assignEnd(3)
Error in loadNamespace(name) : there is no package called 'rcompgen'
 > rcompgen:::.guessTokenFromLine()
Error in loadNamespace(name) : there is no package called 'rcompgen'
 > rcompgen:::.completeToken()
Error in loadNamespace(name) : there is no package called 'rcompgen'
 > rcompgen:::.retrieveCompletions()
Error in loadNamespace(name) : there is no package called 'rcompgen'

As a matter of fact, I never managed to have completion through the use 
of screen... and didn't take time to dig into it!

Hope this helps...

Mathieu.

Unfortunately, this does not seem to solve the issue. My guess is that ESS is having problems reading back from R in this instance. This would explain why it is missing the "TRUE" that would be generated by (ess-current-R-at-least '2.7.0).
