Given the attitude on the gnuplot mailing list, I'd rather change to
pt="0" and make it completely gnuplot's issue that the points are too
small on most terminals (ie they are one pixel and on a 1600x1200 screen
that is really small and almost invisible to my old eyes).

Attached patch is what I would suggest..
