Looks like sed's not filtering out lines before '00-INDEX'; my reading
of POSIX sed specification[1] would seem to confirm the filtering
should work, see:
    [2addr]d
    Delete the pattern space and start the next cycle.

Maybe some regex fun then; what if you remove the anchors (^ and $)?

And anyway, using sed --posix to disable all GNU extensions gives the
expected output here (with GNU sed version 4.2.1).

What's your sed/system, so that I can check what's going on there, and
how to deal with it?

Using 'grep -A $ABIGNUMBER' could be a workaround I guess, but a ugly
one…
