[Rd] relist() is broken when the skeleton is a list with empty list elements

Hi,

relist() is broken when the skeleton is a list with empty list elements:

   > x <- list(1:3, integer(0), 11:14)

   > relist(unlist(x), x)
   [[1]]
   [1] 1 2 3

   [[2]]
   [1] 11  3

   [[3]]
   [1] 11 12 13 14

Hard to believe that such a bug has been around for 6 years (i.e. since
the introduction of relist()) without ever being noticed.

Cheers,
H.
