[Orgmode] org-babel-gnuplot broken today?

[Nigel Beck]

I refreshed today 7.01trans and noticed I couldn't get my gnuplots to
plot anymore: data from a table within the org file is no longer
digested nicely by gnuplot.

To test, I used the snippet below from the worg
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-gnuplot.php:


** Data Table Plot

Plotting data points from a table could look like this:
#+tblname: basic-plot
|   x |         y1 |         y2 |
|-----+------------+------------|
| 0.1 |      0.425 |      0.375 |
| 0.2 |     0.3125 |     0.3375 |
| 0.3 | 0.24999993 | 0.28333338 |
| 0.4 |      0.275 |    0.28125 |
| 0.5 |       0.26 |       0.27 |
| 0.6 | 0.25833338 | 0.24999993 |
| 0.7 | 0.24642845 | 0.23928553 |
| 0.8 |    0.23125 |     0.2375 |
| 0.9 | 0.23333323 |  0.2333332 |
|   1 |     0.2225 |       0.22 |

#+begin_src gnuplot :var data=basic-plot :exports code :file basic-plot.png
set title "Putting it All Together"

set xlabel "X"
set xrange [0:1]
set xtics 0,0.1,1


set ylabel "Y"
set yrange [0.2:0.5]
set ytics 0.2,0.05,0.5


plot data u 1:2 w p lw 2 title 'x vs. y1', \
     data u 1:3 w lp lw 1 title 'x vx. y2'
#+end_src

#+results:
[[file:basic-plot.png]]



Exporting or executing the gnuplot piece, Gnuplot (Gnuplot 4.4 patch
 level 1) complains:

gnuplot> plot data u 1:2 w p lw 2 title 'x vs. y1', \
>     data u 1:3 w lp lw 1 title 'x vx. y2'

         No data in plot


So of course no basic-plot.png is created....

As far as I know, my gnuplots were happy sometime within the past week
refreshing org-mode from git basically daily...
