Junio, would you please pull the following into pu:

This is the pack v4 work to date which is somewhat getting usable. It
is time it gets more exposure, and possibly some more people's attention
who would like to work on the missing parts as I need to scale down my
own involvement.
I've included the latest patches from Nguyn Thái Ngc Duy (sorry for not
handling your name properly) as well. There is no test suite for this
yet, but the added code doesn't seem to regress the existing tests.
Nguyễn Thái Ngọc Duy (31):
