FWIW I think we can be sure that we don't have one. As I said before, I
*completely removed* this function and the test suite passed. That
would seem to constitute sufficient evidence that the code wasn't being
used in any meaningful way.

That would be really helpful. I need to write a new test for 2818 so
it's possible I could fold it into that test, but at the moment I'm
still not following the point of slice_remaining_ranges() completely
(see below).

What about r27? In your example COPY_OF_A/D/G/pi has these initial
remaining_ranges:
'21-29, 34-36, 40-100'
But per your example slice_remaining_ranges() would convert them into:
'21-26, 27-29, 34-36, 40-100'
And r27 wouldn't be merged no?
