Actually it is easy to fix but it may break existing scripts again.
Certainly will break mine. The simple solution would be:
Change output which goes like:

-------
match 00000000/00ff0000 at 4
-----

to

---------
match 00000000 00ff0000 at 4
---

So maybe just make sure the cooked mode works in the future and ignore
all the rest. Or for the raw format (when someone explicitly calls it
with -raw) output it with the space instead of /.

cheers,
