Key improperly placed for splot maps

[Mike S. <mw...@us...>]

The key is not properly placed for splot maps.  The simple test case below 
shows that the key ends up obscuring the plot instead of being outside of the 
plot.  This problem is present in 4.2RC4 and the CVS head.

set key outside right box
set key title "FOODSLKF"
set view map
splot x,cos(x),sin(x)
set key left
replot
set key outside bottom
replot

I modified the key.dem demo.  I added 'set view map' and changed plot to splot 
to see how all the options plotted.  All the automatic key placements seem to 
be misplaced except for maybe outside bottom center.
