[PATCH 00/17] np/pack-v4 updates

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

This contains many bug fixes or cleanups. Also you can now run the
test suite with v4 by setting GIT_TEST_OPTS=--packv4. The test suite
passes now. pack size limit is not officially not supported with v4.
index-pack also learns to convert appended trees to v4 for completing
thin packs (still need to convert commits though)

PS. Nico do you still take patches and then send pull requests to
Junio occasionally, or should I start to CC Junio?
