example file

I have a test PDF with a word written in black (C=M=Y=0, K=100).
I am using gs -sDEVICE=epswrite to convert it into an EPS.
With gs 8.54, the generated eps sets the color with "K" which is "{0 G}" and
"G" is "{255 div setgray}", so this becomes 100% K.
With gs 9.05, the generated eps sets the color with "35 31 32 rG" where "rG" is
"{3{3 -1 roll 255 div}repeat setrgbcolor}", so this becomes 86% C, 88% M, 87%
Y.
This causes bad results when I make color separations.
Using -dUseFastColor fixed the problem with black.
Is that the solution until there is an eps2write?
