[Rd] Changes to environments in R-devel

I've just committed some changes to R-devel which affect environments. Specifically:

> f <- function(x) 1
> environment(f) <- NULL

Warning message:
use of NULL environment is deprecated
> environment(f)

<environment: base>

There may be some places where I've missed putting the conversion in place, and use of NULL will cause an error; please let me know if you find any of those. The intention is that NULL will be usable with warnings through to the end of the 2.3.x releases.
