Yes, the seen-flag state in them is critical information then.

I was thinking about making the index file code more resistant to simply
giving up and rebuilding the index, so that it would try to preserve the
flag state as long as possible. Actually I don't think it has happened
to pretty much anyone with the current code. But still theoretically it
could use a few more fixes. :) This is also useful for dbox if it's
being run in "keep flags/keywords only in index files" mode (I guess
this option could just as well be added for mbox/maildir if someone
wants).

Maybe I'll also some day write code that will automatically convert the
endianess correctly. :) At least for the important fields (header, uid,
flags, keywords) and drop all the rest.
