[O] using Cygwin Gnuplot with org-babel-gnuplot

[Alexander Vorobiev]

Hi,

It is mentioned in
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-gnuplot.html#sec-2_1
that there were some problems with gnuplot on Windows machines. I came
up with a small fix which makes it possible to use Cygwin version of
gnuplot with org-mode. The change is in the org-babel-execute:gnuplot
function where I added passing of optional argument to
org-babel-process-file-name:

before:
(org-babel-process-file-name script-file))))

after:
(org-babel-process-file-name script-file t))))

The argument forces the function not to add backslash prior to ":"
character which prevented gnuplot from finding the script for
execution. I hope somebody will find the fix useful. Unfortunately I
don't know if the fix breaks anything on Unix/Linux/Mac.

Thanks
