Fair enough. The days when we supported a.out dumps are obviously long
long gone, and aren't coming back.

So I am not adamant that it has to be done in the dumper, and I
probably just have that historical "we have multiple different dumpers
with different rules" mindset that isn't really relevant any more.

I wouldn't object. It's not like there's any foreseeable new core dump
format that we'd expect, and the indirection makes the code flow
harder to follow.

Not that most people look at this code a lot.
