If you just replace the newlines with "<br>" then it will be escaped
and printed as "&lt;br&gt;", so you need to parse it into an x-expr or
generate a cdata with:

(make-cdata #f #f "<br>Unescaped")

You want to use statements, so you can put ? for the input and the
sqlite library will quote the single quotes for you.
