Fixed both in the main and in the release candidate branches.

Technical note:

When you zoom, gnuplot rereads the coordinates, but when you send the
data in-line (plot '-') gnuplot can't read them again. This doesn't
happen when you write the coordinates to a file; I was said this will be
fixed in the next gnuplot release. In the meantime, data will be sent to
maxima.gnuplot_pipes as in plot2d.

You can see the same problem if you type:

gnuplot> plot '-' t '' w p ps 5
input data ('e' ends) > 1.0 3.0
input data ('e' ends) > 2.0 4.0
input data ('e' ends) > e

Thanks again for your report.
