Hi,

this is the fourth version of my patch series which aims to implement a
way to pass config entries via the environment while avoiding any
requirements to perform shell quoting on the user's side.

Given that the What's Cooking report notes that my third version is
about to be dropped dropped because the `--config-env` way of doing
things is preferred, I've now adopted that approach. I've taken the
patch which Peff posted originally (with one change strchr->strrchr) and
added documentation and tests to it.

This patch series still includes my old proposal as it would actually be
a better fit for our usecase at GitLab I have in mind, which is to put
all configuration which applies to all git commands into the commands
instead of using a config file for this. I have structured the series in
such a way though that those patches come last -- so if you continue to
think this approach shouldn't make it in, please feel free to drop
patches 3-6.

Patrick
