[AUCTeX] AucTeX and Inkscape -shell-escape

[Nicolas Brouard]

Since Inkscape is able to incorporate TeX code , I was wondering if AucTeX 
could include the "-shell-escape" option to pdflatex command.
This option seems to have been discussed in 2005...

The idea, has presented in this example: 
http://distrib-coffee.ipsl.jussieu.fr/pub/mirrors/ctan/info/svg-inkscape/InkscapePDFLaTeX.pdf
 is to compile a LaTeX file from AucTeX and to execute inkscape with a command 
line during the LaTeX compilation. 

The \write18 facility of TeX could be a window to insecurity as any shell 
command. But from within Emacs/AucTeX I am not highly exposed.

In order to implement it in AucTeX and because I also need the --synctex=1, I 
did a workaround by changing in tex.el:
(defvar TeX-synctex-tex-flags "-shell-escape --synctex=1"
 "Extra flags to pass to TeX commands to enable SyncTeX.")

There is probably a way to add a clean independent defcustom with a more 
specific name related to shell-escape, but I don't know how.

Thanks for your help,
