Hello all,

as I recently updated org, I seem to have run into a bug with ob-gnuplot
(or ob more generally) where data from a table are not interpreted
correctly.  Specifically, if the first column entry in a row is a
negative number, the data file created for use by gnuplot consists of
only - signs, not the actual numbers.

This table, for instance,

#+begin_src org
,#+name: data
|  x |  y |
|----+----|
| -4 | 16 |
| -3 |  9 |
| -2 |  4 |
| -1 |  1 |
|  0 |  0 |
|  1 |  1 |
|  2 |  4 |
|  3 |  9 |
|  4 | 16 |
,#+TBLFM: $2=$1^2
#+end_src

when converted into a file for use by gnuplot for the following script

#+begin_src org
,#+begin_src gnuplot :var d=data :file t.png :results file
  plot d
,#+end_src
#+end_src

looks like this:

,----
| --------------
| --------------
| --------------
| --------------
|  0	 0  
|  1	 1  
|  2	 4  
|  3	 9  
|  4	 16 
`----

I've not yet had a chance to track down why this might be.

Thank you,
eric
