This is more of a follow-up question than an answer :)

The enclosed patch mutes the warnings. Why are the braces needed and
what are they "doing"? The format seem to work fine with this patch.

BTW Dhiru, I also tried the format on a db without a master password
set. This was not detected and apparently this is not the same as a
nullstring password so john started to try cracking and will prbably
never succeed. Is there a way you could detect this situation, maybe in
mozilla2john already?
