This is not a bug, this is a gnuplot "feature" -- the graph appearance
depends on selected terminal. Gnuplot is not a WYSIWYG program.

gset term post eps solid "Helvetica" 20

(you may also want to add "mono" explicitly, though it is a default)

try "13;;" instead of "*;;"

I cannot reproduce that -- dashed line in ps stays dashed in pdf.
I am using older epstopdf (2.5) which comes with RedHat 7.3 (tetex-1.0.7-47
rpm package).
