markdown 1.12

• Provided three internal functions html_document, html_vignette, and pdf_document as compatibility layers to functions of the same names in the rmarkdown package (thanks, @jangorecki, #108). See the appendix in vignette('intro', package = 'markdown') for details.

• The default HTML template no longer wraps meta variables include-before and include-after inside <div></div>, because their values may contain incomplete HTML tags, e.g., include-before = '<div>' and include-after = '</div>'.
