C++: Change back highlighting of types

The type highlighting change part of the recent patch
4a2a17af8a didn't seem to
please much from a visual point of view. It's a better
idea to keep the type highlighting as it was for now
and in the future try again the approach with an explicit
option and perhaps a more restrictive context.

The other patch is not reverted entirely because it does
fix a couple of bugs.
