Hello,

As of 6311cfaf9 (init: do not set unnecessary core.worktree, 2016-09-25), "git init --separate-git-dir" no longer sets core.worktree (test below). Based on the commit message and the corresponding thread [1], I don't think this change in behavior was intentional, but I wasn't able to understand things well enough to attempt a patch.

Thanks.
