[PATCH] Add test case for running from a subdirectory with GIT_WORK_TREE

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

This one is ugly (and not intended to submit to git.git), but
it shows how to reproduce the issues.  You can run it with
arg "--normal" to see it works just fine without GIT_WORK_TREE.
