David, if you think the changes you've made are an improvement, then
please check them in.  I don't have a strong opinion about what to do
here.  My only thoughts are that this is a limitation of gnuplot that
we can't really work around (similar to the way that colors were
specified in the past).  If we want to have specific behavior (certain
marker types and sizes, line colors, etc.) then gnuplot must provide a
way for us to reliably specify those things.  It is not going to work
for us to have to know the details of every possible gnuplot terminal
driver in order to get the appearance right.
