Re: [GSoC] Designing a faster index format - Progress report week 13

A note on how JGit would work here. Java has none of the fields
that constitute statcrc. I guess we would write zero here when
creating new entries. Git could recognize that when checking status
and simply assume "clean" unless mtime or st_size says otherwise.

Even though it may not be the end of the world, that is certainly
bad. Recording the constituent fields separately without the statcrc
microoptimization, thereby not shaving a handful of bytes per the
index entry, is not the end of the world either in the same sense,
which leads us to question the benefit we would be getting from such
a change.
