[Rd] documentation on seek needs update

[Vadim Ogranovich]

 Hi,
 
I wondered how seek() deals with large (>2GB) files. The help says that
the 'where' arg should be an integer, while the release notes for 2.0.0
say

    o	seek() on connections now accepts and returns a double for the
	file position.	This allows >2Gb files to be handled on a
	64-bit platform (and some 32-bit platforms).
 
I assume that the help file just had not been updated, correct?
 
Thanks,
Vadim
