I stick by the statement that the fillstyle specifier is not valid
syntax for any version of gnuplot.  Here's what happens in 4.4.3:

gnuplot> set object  3 rect fc rgb "#fffff0" fillstyle transparent noborder
gnuplot> show object 3
        object  3 rect from 0, 0, 0 to 0, 0, 0
        object  3 back lw 1.0 fc  rgb "#fffff0"  fillstyle   solid 1.00 noborder

Notice that the keyword "transparent" has been ignored since it
didn't have anything to modify, so it picks up the actual
fillstyle from whatever you have set as a default.


But I guess what you are noticing is that in 4.6 coordinates given
in screen space are clipped to the screen, while coordinates given 
in graph space are clipped to the graph.  In both cases it is not
useful to specify a coordinate outside the range [0:1].

Here's one way you could do it to avoid clipping to the graph:

  M = 0.1
  delta = 0.01
  set bmargin at screen M
  set tmargin at screen 1-M
  set lmargin at screen M
  set rmargin at screen 1-M

  set obj 2 rect behind from screen M,M to screen 1-M, 1-M
  set obj 2 fc rgb "white" fillstyle solid noborder

  set obj 1 rect behind from screen M+delta, M-delta to screen 1-M+delta, 1-M-delta 
  set obj 1 fc rgb "black" fillstyle solid noborder

  plot ... whatever
