Yeah, for historical reasons GIT_WORK_TREE defaults to $(pwd) when
GIT_DIR is explicitly set.
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.
Should this important warning be part of the git(1) documentation on the
environment variables (and possibly other places) given the consequences
of this case? It wasn't something I'd appreciated from a simple reading.
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.
