That's a good question.  I can't yet think of a reason to prefer one way over 
the other.

My gut feeling is that we should display such lines as context lines regardless 
of whether they happen to match.

(One thing is certain: if we choose to display a context line that happens to 
match as as matching line, we must not re-start the counting of context lines.)
