If --xetex is specified, pandoc produces latex suitable for processing by xelatex, and markdown2pdf uses xelatex to create the PDF. Resolves Issue #185. This seems better than using latex packages to detect xetex, since not all latex installations will have these. git-svn-id: https://pandoc.googlecode.com/svn/trunk@1737 788f1e2b-df1e-0410-8736-df70ead52e1b
