On base::rank

Indeed.   Interesting that nobody has noticed till now,
even though that part has been world readable since at least 2008-08-25.

Note that the R source code is at
     http://svn.r-project.org/R/
and the file in question at
     http://svn.r-project.org/R/trunk/src/library/base/R/rank.R

where you can already see the new code
(given that 'x' was no longer needed, there's no need for 'xx').
