[PATCH 0/5] Updates for git-http-backend

This patch series applies to pu.  It adds a GIT_PROJECT_ROOT environment
variable, which makes git-http-backend much easier to configure, and it
updates the documentation to add more useful examples and to clarify some
things.

I originally posted this same series as a single patch in one of the replies
to Return of Smart HTTP.  Here, I'm posting it as a set of proper series of
patch, each of which is a unit and has a proper signed-off-by line.
