This is a known issue.

In the POV-Ray SDL, block comments extend from the initial `/*` to the
/matching/ `*/`, allowing them to be nested (which is handy if you want
to comment-out part of your scene but that part already contains block
comments).

This differs from most other programming languages, where a block
comment extends only to the /next/ matching end token, and can not be
nested.

The editor component used in POV-Ray for Windows (which is also
responsible for the syntax highlighting) is a 3rd party component, which
was not specifically designed to cater to the peculiarities of POV-Ray's
SDL, so I suspect it would be difficult to coax its syntax highlighting
into colouring POV-Ray SDL block comments properly.

Since we want to get rid of that 3rd party component anyway, I don't
think we will do anything about this issue (except possibly re-define
the POV-Ray SDL itself, as I suspect the nested block comments may be an
issue with other syntax-highlighting editors as well).
