And it *WILL* be that way til the end of time.  Unless you are at
the top level of your working tree, you are supposed to tell where
the top level is with GIT_WORK_TREE when you use GIT_DIR.  Always.

And that is the answer you should be giving here, not implicit
stuff, which is an implementation detail to help aliases.  I do not
know how things will break when the end user sets and exports it to
the environment, and I do not think we would want to make any
promise on how it works.
