eaten character in X11 - Re: et origin

[Petr M. <mi...@ph...>]

Here is a more improved bug report compared to that I've sent to Ben and 
bu...@oc...:


In Octave 3.2.0, I've noticed a missing ("eaten") character when pasting 
several commands by mouse into Octave or when plotting many plots from a 
script file (under Linux and X11 gnuplot terminal). For example, the 
following is reproducible on my computer -- paste the following by middle 
mouse button:

clf
subplot(1,2,1); title("fig 1")
subplot(2,2,2); title("fig 2")
subplot(2,2,4); title("fig 3")

which leads to:

tmp|16:57:30|11> clf
tmp|16:57:30|12> subplot(1,2,1); title("fig 1")
tmp|16:57:31|13> subplot(2,2,2); title("fig 2")
tmp|16:57:31|14> subplot(2,2,4); title("fig 3")

multiplot> et origin 0, 0
           ^
           line 30: invalid command


It happens in this sequence of commands sent to gnuplot:

	fputs (plot_stream, "set multiplot;\n");
	fputs (plot_stream, "set origin 0, 0\n");

in octave/3.2.0/m/plot/__go_draw_figure__.m

The problem vanishes if I add \n into the first command, e.g.
        fputs (plot_stream, "set multiplot;\n\n");
Note that adding ";" or fflush() does not help.

I have tested older gnuplot releases, and it seems that gnuplot earlier than 
the patch below works correctly:

* term/x11.trm (X11_set_font ENHX11_put_text): Initialize enhanced text 
  processing to use most recently requested font rather than the default 
  font.

Ethan, can you please check it?
