Now that 3.0.0 has been released, 2.9.16 is obsolete.  Please consider
upgrading.

See the NEWS file for Octave 3.0.0.  The __gnuplot_X__ functions no
longer have any effect on plots generated with the higher level plot
functions like plot, semilogx, mesh, etc., and will be removed from a
future version of Octave (they are already gone from the main
development branch in CVS).
