pdflatex with simple Feynman

[Haines Brown]

I found the reason why the Feynman diagran fails to show up in my 
document. When I compile the LaTeX file with C-c-c in Emacs, it 
converts the LateX command to pdflatex. 

The Feynman diagram does not show up because the fenymp-auto package 
requires runing the pdflatex --shell-escape twice. So I compile
my .tex source docuement from a terminal with the needed command and 
the diagram displays correctly.
