My mistake, I took "pre-scan" as one pass and then "highlighting" as
another pass. It seem perfectly possible to use a single pass/scan of
the source code to manage syntax highlighting - as long as state and
context is carried forward when language syntax is detected that could
span multiple lines (like { or (* style comments).
