[ESS] Ess-source-directory in windows

[Liaw, Andy]

Thanks, Tim, but I don't think that will solve Matt's problem.  If I'm not
mistaken, what Matt wants is to have ess-source-directory set to the
"R-source" subdirectory of the working directory for the iESS process.
E.g., if I start an R process in, say, c:/project1, then c-c c-d allows me
to dump an object to a file in c:/project1/R-source.  However, if I then do
c-c c-l in that buffer, I get the error that Matt mentioned (seems like
directory separators are somehow dropped).  This works correctly in GNU
Emacs.  The only setup where we found the problem is XEmacs on Windows XP.

Cheers,
Andy
