Although I fixed a number of bugs in basic range-set manipulation code
(5 years ago), I have no experience with or knowledge of the code
actually dealing with range-set manipulation in relation to diffs, so
I'm not a domain expert by any means, and I'm _still_ trying to wrap
my head around that code.
That said, I left some comments on the individual patches suggesting a
simpler and more correct fix for the crash. (Despite that suggestion
for fixing the crash, I still can't say whether the actual
computations performed by the existing code are correct, since I still
don't understand that aspect of it.)
