Once you're doing typesetting like that, I think it would be even better if you start replacing keywords with special symbols and reformatting the lines to some canonical representation. That would make it way easier to read.
Wow, that looks way better than I thought it would. I'm saddened to hear that after all the effort into the new VS text system it isn't capable of doing all you wanted.
But, it would be nice if VS supported italics, various font weights, and small caps.
