git-init: set core.worktree if GIT_WORK_TREE is specified
Now you can do the following to create a repository which has a separate working tree: /tmp/foo$ export GIT_DIR=/tmp/bar /tmp/foo$ git --work-tree . init Initialized empty Git repository in /tmp/bar/ /tmp/foo$ git config core.worktree /tmp/foo Signed-off-by: Matthias Lederhofer <matled@gmx.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
