box fill bug in emf.trm

[Allin C. <cot...@wf...>]

There's a bug in emf.trm, on line 836 in current CVS

    /* Force re-evaluation of linetype next time we draw a line */
>   emf_color = color;
    emf_linetype = LT_UNDEFINED;
    emf_dashtype = LT_UNDEFINED;

If you plot using boxes with a fractional fill, the line 
"emf_color = color" has the effect of producing progressively 
paler boxes, e.g. if the fill is 0.6, each box has saturation of 
0.6 times the previous box.  

I have found no ill effects from simply deleting this line.

Simple test case:

set term emf
set output 'bad.emf'
set style fill solid 0.6
set yrange [0:.4]
plot '-' using 1:2 w boxes
1 .1
2 .2
3 .3
4 .2
5 .1
