Ok, at that point I certainly agree.

As long as we're talking about a single flat file, I don't think it would be all that painful to have a totally new index format. The original format was (obviously) designed to be just mmap'ed and turned into a C array with no real parsing.

But once we started building a separate index data structure with internal structure _anyway_ (for the extended in-memory flags and the filename hashing), a lot of the reasons for the original format kind of went away.
