Details:

Using legend() in a quiver3() plot causes script execution to halt with the
message

error: data(3,_): but data has size 2x1
error: called from
    __gnuplot_draw_axes__>__gnuplot_write_data__ at line 2144 column 11
    __gnuplot_draw_axes__ at line 1734 column 9
    __gnuplot_draw_figure__ at line 164 column 17
    __gnuplot_drawnow__ at line 86 column 5


This only seems to happen with graphics_toolkit("gnuplot"). Toolkits "qt" and
"fltk" seem to work fine. A program which displays the error is attached as
"quiver3legend.m". The error occurs in Octave 4.2.2 and 4.4.0 for MS Windows,
as well as in 4.4.0 for Cygwin, all when using gnuplot.
