The problem here seems to be that ` is defined in the syntax table to be a quote character, so `parse-partial-sexp` will skip to the end of the buffer (or the next ` character) in font-lock-fontify-syntactically-region. I'm trying to familiarise myself with how font locking is supposed to work -- anybody know what I should be poking into to get this to work better? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
