[Rd] Warning message when items of Hmisc are masked by loading a package.

[Joris Meys]

I know the masking message is standard behaviour. It is the warning mesage

> Warning message:
> In identical(get(., i), get(., lib.pos)) : ignoring non-pairlist attributes

that puzzles me. And that's something I noticed only in 2.12.1

Cheers
Joris
