The way Octave communicates with gnuplot was changed in the 2.9.x
series only.  That was one of the reasons for the split in version
numbers.  Othere reasons were sparse matrix support and 64-bit array
dimensions and indexing.  All these changes are "risky" so it seemed
like a good time to split the CVS archive so people would have
something reliable to work with (2.1.x).

The new names (__gnuplot_plot__, etc.) were introduced in the 2.1.x
series so that people could start using them over time, while the old
names are still available (with warnings).  But in 2.1.x the new names
are just aliases for the old names.  In 2.9.x, things work a bit
differently and the old names will be gone by the time we have a 3.0
release.
