Thanks - looks great. (side note to anyone who's interested: copy/pasting
from the website in IE & FF doesn't keep the coloring, unfortunately (I
believe it's because it's in CSS & these browsers don't bother to go &
gather the CSS & inline it into the copied snippet) - but Chrome does the
right thing. So if you want to put colored output in webpages, emails, etc -
copy/paste from the demo while using Chrome!)

Thanks for the help, Tanya.

I confirm it is now working correctly (as much as it can work in C++03).

I'll see if I can send out a CR to add C++11 support to the website tonight
- though it'll require deploying libc++ to the demo server for any library
usage, of course.
