[Rd] [R] HTTP User-Agent header

I wonder if it would not be better to make the user agent string 
something that is configurable (at the time R is built) rather than at 
run time. This would make Seth's patch about 1% as long. Or this could 
be handled as an option. The patches are pretty extensive and allow for 
setting the agent header by setting parameters in function calls (eg 
download.files). I am not sure there is a good use case for that level 
of flexibility and the additional code is substantial.

The issue that I think arises is that there are potentially other 
systems that will be unhappy with R's identification of itself and so 
some users may also need to turn it off.

Any strong opinions?
