[Rd] password-protected HTTP proxies

[ripley@stats.ox.ac.uk]

I have added code to R-devel to handle HTTP proxies which require 
username/password (basic) authentication.  I read the HTTP/1.0 (and /1.1) 
specs and looked at the user interface of wget, but I have no such proxy 
to try.

If anyone can try such a proxy, I would appreciate a report on

(1) does it work and

(2) if you are already using wget, do the environment variables you set 
for wget work unchanged for my code?

and of course if not, the code patches needed to make it work.

Brian
