Fix website demo's string highlighting behaviour (#942) 

Fixes #935:
* String literals that include `\z` escape sequence followed by newline
characters are now correctly highlighted.
* Unescaped backslash (`\`) character at the end of the line no longer
acts like the `\z` escape sequence inside string literals when
highlighting.
