I think let's keep the default for now. It has a plus side: the backends 
can return buffer lines with syntax highlighting applied. 
semantic-symref looks like that too.

An added face might be nice, but probably one that sets the background 
color.

I think so. And hopefully, the "find definitions" search will result in 
one unique result most of the time.
