/* is trickier, you have to scan characters until you find */ and then POV-Ray
supports nested multiline comments. So if you find a second /* in a comment you
either have to start a counter or use recursion otherwise you'll miss the true
end of the comment.

Lots of parsers are clever, they can skip parts of words when they are sure that
there is no other option than that specific keyword even if they are only half
way parsing that word. But in the end you still have to visit a lot of
characters.

My POV-Ray HTML highlighter (https://ingoogni.nl/download/) parses a POV-Ray
file using regular expressions, not the most elegant way to do it. It properly
handles the nested comments.
