Unfortunately, it seems that the proposed method using /AUCTEXINPUT does
not work with file name with space.  The sample I'm using is a file named
"ppp qqq.tex" with the content:
------- ppp qqq.tex --------------------------------------------------
\documentclass{article}
\begin{document}
Hello, World
\(xyz\)
\end{document}

%%% Local Variables: 
%%% TeX-master: t
%%% End: 
----------------------------------------------------------------------

I'm currently stuck up with this situation.  It's hard to cope with
unusual file names...
