    fix: Highlights overlay can get added to unsupported buffer
    
    Before this fix, a highlight could be added to an unsupported buffer
    such as *scratch* buffer. When you try to remove it, you get an error
    message. This is all confusing.
    
    Now with this fix, trying to add a highlight in an unnsupported buffer,
    you only get a message and the overlay is not to be added.
