My blog (http://texdev.net) is about TeX and LaTeX, so I'd like to use TeX code highlighting. Is there a way to set WP-MarkDown to pass information to Prettifier about which highlighting parser to use? Based on the StackExchange extensions, I tried using a 'magic comment' line of the form
<!-- language: lang-tex --> and similar, but this does not seem to work. I also had a look at the settings for a 'default language' (I hardly ever need anything except TeX), but again drew a blank.
