Give me a couple of days and I'll look into how back-patchable the
tests can be made, and see what else we can test.  Perhaps it's not
strictly necessary to back-patch the fix further than 15, but I think
we should definitely consider it, and I don't like the idea of not
having the tests accompanying the change.

If you have any ideas about how to write a more efficient version of
advance_to_record_splitting_zone() (or I guess that should really be
advance_to_record_header_splitting_zone()), and generally how to make
the perl better, and how to get those constants we need from the
source or binaries, then I'm all ears.
