One thing we should be able to do (and must do) better is to
validate that core.worktree in the relocated config file actually
points at the right place. Unsetting before comparing may let us
compare the relocated one in .git/modules/$1/config with the one
that is embedded in the working tree (hence no .git/config), but the
way your "how about this?" patch does, we wouldn't catch a possible
breakage to the relocation code to point core.worktree to a bogus
location, I'm afraid.
Perhaps squashing this to 7e8e5af9 instead?
