R devel - Dec 1999 - split nukes names() (PR#371)

> split(c(a=1,b=2),c(1,2))
$"1"
[1] 1

$"2"
[1] 2

The documentation does not *promise* that names will survive, but in
Splus3.4, they do. This broke a function that worked under S+ that used
the names attribute of elements in the components returned by split.

I don't think that names in x should be preserved here.  The names of
the returned list are obtained from the levels of the split factor f
(which, in your case, are "1" and "2").
