[PATCH 0/8] Add 'ls-files --json' to dump the index in json

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This is probably just my itch. Every time I have to do something with
the index, I need to add a little bit code here, a little bit there to
get a better "view" of the index.

This solves it for me. It allows me to see pretty much everything in the
index (except really low detail stuff like pathname compression). It's
readable by human, but also easy to parse if you need to do statistics
and stuff. You could even do a "diff" between two indexes.

I'm not really sure if anybody else finds this useful. Because if not,
I guess there's not much point trying to merge it to git.git just for a
single user. Maintaining off tree is still a pain for me, but I think
I can manage it.
