So long as we're in web-browser-compatible land, we can parse XHTML with
an HTML parser that knows about CDATA.  And when we move out of it,
we're also leaving commented <script> and <style> contents behind.

I'll grant there are other pathological edge-cases due to the ways
people abuse markup.  That's one very good reason none of the modules
I mentioned defaults to stripping comments:-)
