[R] Rectangle height in lattice xyplot key

Dear All

I have a problem with the height of the boxes in the key in the following.
(The text is over 2 lines to  accentuate the problem of no space 
between the rectangles.)
Is there an easy way to put a space between the rectangles; size 
controls the width but there appears to be nothing for the height?

            key = list(corner = c(0.8,0.8),
                       cex   = 0.6,
                       title = "Functional Groups",
                       cex.title = 0.7,
                       columns = 1,
                       padding.text = 4,
                       text  = list(label = 
                       points = list(pch = c(1,3,4,20,16),
                                     col = c(2,3,4,5,6)),
                       lines = list(col = c(2,3,4,5,6),
                                       size = 2),),
                       rectangles = list(col = c(2,3,4,5,6),
                                         size = 1,
                                         border = FALSE)) )

I could get things to work when the legend was on top 
using  http://finzi.psych.upenn.edu/R/Rhelp02/archive/46654.html on 
something similar
but could not get it to work in the last panel of a multipanel plot.
