One thing that we did not have to worry about when git-sh-setup was
invented is GIT_WORK_TREE and its cousin core.worktree.  When the user
uses GIT_DIR _but_ wants to work from a subdirectory of the checked out
work tree, the user _must_ tell git where the top of the work tree is; in
other words, setting and exporting only GIT_DIR is a misconfiguration.

I have a suspicion that "the whole different bug" is what bit you --
perhaps some places need to also set and export GIT_WORK_TREE as well when
the do GIT_DIR.
