  Pad binary data to gnuplot with a space

  * scripts/plot/private/__go_draw_axes__.m: Add a space to the end of each
  binary record.  Fixes the "nset obj 1;\n <- line 0: invalid command".

What problem was the extra blank line attempting to solve?  Maybe it
works with some versions of gnuplot and not others?  I'm using 4.6.0.
